During the late 1990s, Sammy Sosa rookie cards became some of the hottest commodities in the hobby.
Demand soared as he and Mark McGwire chased Roger Maris's single-season home run record in 1998.
With every home run he hit, prices seemed to go higher...
Luckily, there was plenty of supply to meet that demand.
After all, Sosa made his rookie card debut during the hobby boom of the early 1990s.
And print runs were massive during that period.
The only question collectors faced was: which Sosa rookie should they buy?
Sosa rookies appeared in multiple sets.
In this article, we'll take a look at the good and bad of each of them.
Let's jump right in!
1990 O-Pee-Chee #692 Sammy Sosa Rookie Card
Estimated PSA 10 Value: $800
In 1911, two brothers named John and Duncan McDermid founded the O-Pee-Chee confectionary company in Ontario, Canada.
Initially, O-Pee-Chee only produced chewing gum.
But, over the years, the company ventured into other markets and, by the 1930s, took a crack at the trading card market by producing baseball and hockey cards.
By the 1960s, O-Pee-Chee had a marketing agreement with Topps, allowing it to produce baseball cards that essentially mirrored the Topps design.
In fact, from 1965 to 1992, collectors could buy O-Pee-Chee baseball cards that looked nearly identical to the Topps versions.
Some of the O-Pee-Chee baseball sets from those years featured cards with the O-Pee-Chee logo right on the front.
But most, like the 1990 O-Pee-Chee baseball set, were not as easily identifiable unless you turned them over to see the French text and O-Pee-Chee trademark on the reverse (see example below).
Because the 1990 O-Pee-Chee production run was limited and the card stock wasn't as great, finding pristine-condition examples of Sosa's rookie can be challenging.
1990 Topps Tiffany #692
Estimated PSA 10 Value: $275
When Donruss and Fleer entered the baseball card market in 1981, the increased competition forced Topps to up its game to remain on top.
In 1984, Topps released a high-quality premium version of its flagship release sold exclusively as a boxed set known as the "Collectors' Edition."
Over time, collectors would simply refer to them as "Topps Tiffany" sets and Topps continued to produce them until 1991.
The imagery and design of the Tiffany cards were identical to the base cards.
However, the card stock was far superior and had a glossy finish.
If you hold a 1990 Topps Sammy Sosa and a 1990 Topps Tiffany Sammy Sosa in your hands, you'll easily spot the differences.
However, if you're looking at examples online, you can also tell the difference by looking in the bottom right corner of the reverse sides.
You'll notice an "E*" next to the Topps trademark statement on the standard Topps version, while the Tiffany version omits it.
In the image below, follow the red arrows to see what I'm talking about.
Because Topps printed far fewer Tiffany versions of the Sosa rookie card, they can command a substantial premium over the base version.
Finally, I should note that some collectors don't consider the Tiffany version a "real" rookie card, but I chose to include it in this guide for those that do.
1990 Bowman Tiffany #312
Estimated PSA 10 Value: $250
During the run of Topps Tiffany sets from 1984 to 1991, Topps also released Tiffany versions of their Bowman sets in 1989 and 1990.
Like the 1990 Topps Tiffany Sosa card, some in the hobby may not consider his 1990 Bowman Tiffany card a "true" rookie card either.
Either way, the market certainly prices it as a rookie, considering its value exceeds that of Hall of Famers in the set like Nolan Ryan, Cal Ripken Jr., Rickey Henderson, and Tony Gwynn.
Just as you'd expect the Topps Tiffany Sosa card to be on higher-quality card stock and with a nice glossy finish, so too is its Bowman counterpart.
One way to tell the difference between a standard Bowman and Bowman Tiffany card is to look at the reverse.
The Tiffany version will appear much cleaner and whiter while the standard version is more of a dull gray.
Some estimate that 6,000 Bowman Tiffany sets hit the market compared to 5,000 Topps Tiffany sets.
Unlike the oversized 1989 Bowman cards, many collectors were delighted to see Topps revert to standard 2-1/2" by 3-1/2" dimensions for its 1990 Bowman sets.
1990 Fleer Canadian #548 Sammy Sosa Rookie Card
Estimated PSA 10 Value: $175
Many collectors may be unaware that Fleer also targeted the Canadian baseball card market in 1990.
Seeing Topps's success with O-Pee-Chee, Fleer released a complete 660-card parallel to their flagship baseball set made in Canada.
However, Fleer's attempt to penetrate the Canadian must not have been successful, given this was the only year they printed a Canadian parallel.
One glaring issue immediately jumps out.
Unlike O-Pee-Chee cards that contain English and French text, the Fleer Canadian cards are exclusively in English.
I don't know how much that had to do with the low interest from Canadian collectors, but it's noticeable.
Aesthetically, the Canadian versions mirror their U.S. counterparts.
The only way to distinguish the Canadian issue is by looking at the copyright details on the bottom of the reverse sides.
Whereas a regular Fleer card will state "(C) 1990 FLEER CORP., PHILA.,19141 PRINTED IN U.S.A.", the Canadian versions read "(C) 1990 FLEER LTD./LTEE PTD. IN CANADA."
Production runs were much more limited in Canada than in the United States.
And, since relatively fewer of them exist and made their way into PSA 10 holders, they command a premium versus the U.S. versions.
1990 Sportflics #81
Estimated PSA 10 Value: $75
This 1990 Sportflics issue is another card that receives mixed opinions from the hobby regarding its status as a "true" rookie.
Regardless of your opinion, its design stands out from the other cards on this list in an obvious way: its plastic lenticular coating on the front.
Underneath that lenticular surface sit two entwined images that will mimic movement depending on your vantage point.
When you rotate the card from side to side, Sosa will appear to swing and follow through.
From 1986 to 1990, collectors could find these Sportflics sets as exciting alternatives to the standard, boring, "motionless" designs of other sets.
Today, they may seem like gimmicks to some.
But, in the 1980s, the sports card market was on fire and companies were doing anything to stand out from the crowd.
I personally enjoy these cards as a nice blast from the past.
1990 Bowman #312 Sammy Sosa Rookie Card
Estimated PSA 10 Value: $65
Following the successful revival of the Bowman brand in 1989, Topps continued with another Bowman release in 1990.
You'll notice they have the same general look and feel from the previous year.
But some things were very different.
One glaring change was Topps' decision to abandon the oversized dimensions of 1989, opting instead for the standard 2.5 inches by 3.5 inches layout.
Like many players in the set, Sosa is shown with a close-up rather than an action pose.
I love the retro Chicago White Sox jerseys and hats with the cursive lettering.
Sure, it would have been nice to see Sosa in action but the retro uniform makes up for it a bit.
Considering the Bowman set is somewhat overlooked compared to other brands of the same year, there are far fewer 1990 Bowman Sosa rookies in PSA 10 holders.
The lower production numbers also support this relative "scarcity."
For that reason, you'll notice that his Bowman rookie is a bit pricier than the other major brands.
1990 Leaf #220 Sammy Sosa Rookie Card
Estimated PSA 10 Value: $50
After a brief hiatus in 1989, Leaf baseball cards returned triumphantly in 1990 with an overhaul in design standards.
With Upper Deck making a splash in the market in 1989 with their premium, high-quality set design, it was clear to Donruss that they needed to step up their game.
The market was changing and collectors wanted higher quality.
So Donruss responded with 1990 Leaf.
The foil-wrapped packs were early hints that the cards would deliver a different experience from the typical Donruss product.
White borders, fantastic photography, and a classy design sent collectors into a frenzy.
Many were willing to pay higher than retail prices for a 15-card pack.
To say collectors responded positively to this product is an understatement.
As for Sosa's rookie, it was one of the hottest cards in the hobby during the 1990s.
The home run chase between Mark McGwire and him in 1998 only furthered the demand.
In the aftermath of his PED scandal, demand isn't nearly what it once was.
Yet, this card and the set itself remain relics of the late 80s and early 90s hobby boom.
I still think it's funny they showed him bunting...
1990 Donruss #489 Sammy Sosa Rookie Card
Estimated PSA 10 Value: $25
There's no way around it: collectors either love or hate the 1990 Donruss baseball set.
The design, color scheme, and massive print runs leave a bad taste for many collectors.
Personally, I like the set.
I have vivid memories of seeing these cards in stores and hobby shops and ripping through many packs.
For me, it was primarily about chasing down some of my favorite players of the day: guys like Cal Ripken Jr., Ken Griffey Jr., Rickey Henderson, Bo Jackson, Nolan Ryan and many more.
And the rookie class was great, even if Frank Thomas was noticeably absent and Larry Walker was the only one to make it to Cooperstown.
The design never really bothered me.
It was all about the players.
Sosa's rise as a home run machine in the 1990s brought lots of attention to this card back then.
Today, like many in the set, it has fallen by the wayside and lost much of its value.
Along with those of Larry Walker, John Olerud, Dave Justice, Deion Sanders and Bernie Williams, I always wished Donruss would've given Sosa's card the "Rated Rookie" label.
1990 Topps #692 Sammy Sosa Rookie Card
Estimated PSA 10 Value: $25
Donruss wasn't alone in the controversial design department.
Collectors also tended to be on one side of the fence regarding the 1990 Topps look and feel.
Again, I liked this set, regardless of its unique design.
In fact, I enjoyed the multi-color border scheme and still do to this day.
It has so many quirks and that make it unique even in today's market.
The "No Name On Front" Frank Thomas rookie card is, perhaps, the most prominent example.
The card featuring former President George Bush from his playing days at Yale is also iconic.
The scar on Ken Griffey Jr.'s forearm on his second-year "All-Star Rookie" card that sends collectors into a craze trying to find different "variations" of it.
They all get attention.
Had he avoided controversy and ended up in the Hall of Fame, this would have arguably been Sosa's most desirable rookie card.
At least that's the way it usually goes since Topps is the most iconic name in the hobby.
1990 Upper Deck #17 Sammy Sosa Rookie Card
Estimated PSA 10 Value: $25
From the day they first released their debut set in 1989, Upper Deck was known for its quality sports cards.
The card stock was top-notch.
The photography was superior.
And the anti-counterfeit holograms on the reverse sides seemed like something from the future.
Sosa's rookie card exhibits all of those trademark features as the young slugger sits in the dugout with a huge smile on his face.
As young collectors, we always wanted to see the "Star Rookie" symbol in the lower left, and it still resonates with that sense of excitement today.
Just like the Donruss set, despite having a lot of star rookies in its checklist, Larry Walker was the only rookie in this set to make it to the Hall of Fame.
Frank Thomas was also surprisingly absent from this set, too.
Overall, this Sammy Sosa rookie card is solid, but it could've been so much better had Upper Deck shown him in an action pose.
1990 Fleer #548 Sammy Sosa Rookie Card
Estimated PSA 10 Value: $20
Like so many of the other flagship sets during that era, production numbers of 1990 Fleer baseball cards were astronomical.
Unlike the Canadian version, finding these in PSA 10 condition isn't a hard task at all.
They're everywhere.
Still, despite being one of the reasons this era became known as the "junk wax" era, I enjoy this set and its place in hobby history.
Though it contains 660 cards, its checklist is smaller than 1990 Donruss, Score, Topps and Upper Deck.
And the design is unforgettable.
The gleaming white borders augmented by team-colored borders make these cards some of the "crispier" flagship cards from 1990.
For years, it seemed like Sosa would possibly be the only rookie in this set to make the Hall of Fame.
Frank Thomas didn't appear until the 1990 Fleer Update release.
David Justice started hot and then later fell back to Earth.
And Larry Walker seemed on a trajectory as a borderline Hall of Famer.
Walker did end up making it but Sosa's career fell apart.
Name recognition alone, though, keep Sosa's rookie among the most desirable in the set.
1990 Score #558 Sammy Sosa Rookie Card
Estimated PSA 10 Value: $20
Though it may not be his most expensive rookie card, his 1990 Score rookie is arguably one of the best-looking.
I always loved how Score utilized multiple border colors, and the deep blue borders made Sosa's card pop.
What makes this card stand out from the rest of his rookies, though, is the action shot.
Several of his rookies don't have action shots at all.
The others that do have action shots show him batting.
But this is the only where he's running.
And he is absolutely hauling.
People will always remember Sosa for his tape-measure home run blasts and multiple 60+ home run seasons.
But what is often lost in all those home run highlight reels is that he used to be pretty good at stealing bases.
Including his rookie season, Sosa stole more than 30 bases three times in his career.
Based on the field position in the background, it looks like he's heading towards home.
However, it's unlikely he was stealing home plate.
Maybe he was trying to score on a passed ball.
But the most likely scenario is he was beating out a throw at home plate.
Whatever was going on, Sosa was on a tear.
The Sammy Sosa Rookie Card Review
Now that we've gone through the list, here are some of my thoughts on Sammy Sosa's rookie cards:
Most Valuable: Sammy Sosa's most valuable rookie card is his 1990 O-Pee-Chee, which can be worth over $800 in PSA 10 condition.
Least Valuable: Both the 1990 Fleer and Score Sammy Sosa rookie cards are typically considered his least valuable.
My Favorite: I'm partial to his 1990 Topps rookie. I always loved this set as a kid and Sosa's card has a fantastic action shot.
My Least Favorite: None of them really stand out as the absolute worst, but if I had to pick, I guess I would go with his 1990 Bowman card. There's no action shot and the design is more dull than the others.
