You probably have a stack of them in a shoebox. Somewhere between the 1990 Donruss "The Rookies" and a handful of Upper Deck commons, there sits a 1990 Topps Mark McGwire. It’s a clean card. Big Mac is mid-swing, wearing that classic Oakland A’s white jersey, looking every bit like the guy who would eventually break the single-season home run record (before things got complicated).
But here’s the reality. Most of those cards are basically coasters.
I know, it hurts to hear. We grew up thinking these bits of cardboard were our future retirement funds. We treated them like gold bullion. In reality, Topps printed millions of these. Literally millions. If you’re looking at a standard 1990 Topps Mark McGwire #690, and it’s got a little soft corner or some white chipping on the edges, you’re looking at a card that might sell for fifty cents at a garage sale if you're lucky.
But wait. There’s a catch. There is always a catch in the "Junk Wax" era. While the base card is common enough to wallpaper a room with, a few specific versions of this card actually fetch real money. We're talking hundreds, sometimes even thousands of dollars. You just have to know exactly where to look on the card, and honestly, you need a bit of luck.
The Error That Changed Everything: No Name On Front (NNOF)
If you follow the hobby even casually, you’ve heard of the Frank Thomas No Name on Front error from this same 1990 Topps set. It’s legendary. It’s the holy grail of 1990. However, most people don't realize that the printing glitch that scrubbed Frank’s name didn’t just affect the Big Hurt. It hit a handful of other cards on the same printing sheet, including the 1990 Topps Mark McGwire.
It’s subtle.

On the true NNOF error, parts of the black ink are missing from the front of the card. On the McGwire, this usually manifests as missing bits of the black border or a "broken" nameplate. It is exceptionally rare. While the Frank Thomas version is the famous one, a confirmed McGwire printing error from that specific defective sheet is a monster find.
Why did this happen? Basically, a piece of debris—likely a bit of paper or a "hickey"—got stuck on the printing plate. It blocked the black ink from hitting the card stock. Because Topps was pumping these out at lightning speed to meet the insane demand of the 1990s card craze, the mistake ran for a short period before someone noticed and fixed the plate. If you find one of these, stop touching it immediately. Put it in a one-touch case.
Why Condition Is King (And Why Most 10s Aren't Really 10s)
Let’s talk about the "Gem Mint" trap.
You’ll see a 1990 Topps Mark McGwire on eBay listed for $500. You look at your card. It looks the same. You think, "I'm rich." You aren't. Not yet.
The value in 1990 Topps lies almost entirely in the grade. Because these cards were produced in such massive quantities, the market only cares about the absolute best of the best. We’re talking PSA 10 or SGC 10 Gold Label. 1990 Topps was notorious for bad centering. Look at your McGwire. Is the white border on the left the same width as the border on the right? Probably not. Is the top-to-bottom centering off? Usually.
Then there’s the "print snow."
If you look closely at the red nameplate or the dark areas of the image, do you see tiny white specks? That’s "snow." It’s a common printing defect from 1990. To a casual collector, it’s nothing. To a PSA grader, it’s the difference between a $200 card and a $2 card. Honestly, getting a PSA 10 on a 1990 Topps card is a nightmare. The card stock was cheap, the cutting blades were often dull, and the quality control was non-existent.
The Tiffany Version: The Real Hidden Gem
If you want a 1990 Topps Mark McGwire that actually holds its value, you need to check if you have a "Tiffany" edition.
Back in the day, Topps released limited edition factory sets called Topps Tiffany. They weren't sold in wax packs at the local 7-Eleven. You had to buy the whole set from a hobby dealer. They look almost identical to the base cards, but there are two dead giveaways:
- The Gloss: The front of a Tiffany card has a high-gloss, premium finish. If you tilt it under a light, it shines like a modern chrome card. The regular 1990 Topps cards are flat and matte.
- The Back: This is the easiest way to tell. Flip the card over. If the back is a bright, vibrant white, it’s a Tiffany. If the back is that dull, recycled-looking grey/brown cardboard? That’s the common base version.
There were only about 15,000 Tiffany sets produced in 1990. Compared to the millions of base sets, that’s nothing. A 1990 Topps Tiffany Mark McGwire in a high grade is a legitimate investment piece. It’s the version that serious Big Mac collectors actually hunt for.
The Steroid Cloud and the Market's Long Memory
We can't talk about McGwire without talking about the 1998 home run chase and the subsequent fallout. For a long time, McGwire cards were toxic. When the Mitchell Report came out and the Congressional hearings happened, prices cratered. People felt betrayed.
But time heals all wounds in the hobby, or at least it numbs them.
Lately, there’s been a massive wave of "90s nostalgia." The kids who grew up watching McGwire and Sosa are now in their 40s. They have disposable income. They don't care as much about the PED era controversies; they just want to own a piece of their childhood. This has caused a slow, steady rise in the price of high-grade McGwire cards. He might not be in the Hall of Fame (yet), but his impact on the game's history is undeniable. You can't tell the story of baseball without him, and collectors are starting to treat his key cards with that level of respect again.
Spotting a Fake (Yes, They Exist)
It seems crazy to counterfeit a card from the junk wax era, but for the NNOF errors or the Tiffany versions, it happens.
Scammers will sometimes take a regular 1990 Topps McGwire and try to "gloss" it up to look like a Tiffany. Or they'll use chemicals to fade out the name to mimic the No Name on Front error. The easiest way to protect yourself is to look at the "halftone" dots under a jeweler’s loupe. Real 1990 Topps cards have a specific dot pattern. If the dots look blurry or like they were printed from a home inkjet, run away.
Also, check the weight. Tiffany cards are printed on slightly thicker, higher-quality white cardstock. They feel different in the hand. They’re sturdier.
Identifying the Value of Your Collection
So, you’ve found your 1990 Topps Mark McGwire. What’s next?
Don't just look at "Asking Prices" on eBay. Anyone can ask for $10,000. It doesn't mean they'll get it. You need to filter by "Sold Items." That’s the only number that matters. You’ll see that while some "raw" (un-graded) McGwires sell for $1, others—the ones with the right flaws or the right gloss—are moving for real money.

If your card is perfectly centered, has sharp corners, and looks like it just came out of a fresh pack, it might be worth the $20-$30 grading fee. But be honest with yourself. Most cards from that era have "white corners" (wear that reveals the paper underneath). If you see even a speck of white on those corners, it’s not a 10.
Actionable Steps for Collectors
If you’re sitting on a stack of 1990 Topps cards, here is how you should handle the Mark McGwire #690:
- Perform the "Flip Test": Check the back of the card. If it’s bright white, you’ve hit the Tiffany jackpot. Separate it and put it in a penny sleeve and top-loader immediately.
- Inspect the Nameplate: Look for missing ink or "ghosting" around the name "Mark McGwire." Authentic printing errors from the NNOF sheet are rare and highly sought after by error-card specialists.
- Check Centering: Use a centering tool or just eyeball the borders. If the card is shifted heavily to one side, it’s a "common" and likely not worth grading.
- Look for "Snow": If the image is clean and free of white printing specks, it’s a candidate for a high grade.
- Check Sold Listings: Use 130Point or eBay's completed sales to see what people are actually paying for the card in its current condition.
- Consider "Bulk" Grading: If you have several cards that look perfect, wait for a grading special. Sending a single junk wax card to PSA can be expensive once you factor in shipping and insurance.
The 1990 Topps Mark McGwire isn't going to buy you a private island, but it’s a fascinating snapshot of a wild time in baseball history. Whether it’s a fifty-cent common or a $500 Tiffany 10, it’s a piece of the Bash Brothers legacy that still resonates in the hobby today.
