The 1988 Donruss Diamond Kings are the quintessential paradox of the junk wax era. Walk into any card shop today, and you’ll likely find a dusty wax box of '88 Donruss sitting on a bottom shelf, priced so low it’s basically a rounding error. It was the height of overproduction. Millions of cards flooded the market. Yet, for those of us who grew up peeling back that flimsy plastic wrap, the Diamond Kings were the gold standard of "hits" before hits even existed. They were different. They weren't just photos of guys standing in dugouts; they were art.
Honestly, the 1988 set is a weird one. It’s infamous for its blue-and-black borders that chip if you so much as look at them wrong. But those first 26 cards in the checklist? They remain iconic. Dick Perez, the artist behind the Perez-Steele Hall of Fame postcards, brought a certain prestige to a product that was otherwise being printed at a rate that would make the Federal Reserve blush.
The Artistic Legacy of Dick Perez
You can’t talk about the 1988 Donruss Diamond Kings without talking about the man behind the brush. Dick Perez didn’t just paint baseball players. He captured the vibe of the era. While Topps was sticking to traditional photography and Fleer was experimenting with those hideous "cat-scratch" borders, Donruss leaned into the "collector as connoisseur" angle.
The 1988 set marked the seventh year of the Diamond Kings subset. By this point, the formula was perfected. Each team got one representative. It wasn't always the biggest star—though it often was—but rather a player who defined the franchise at that specific moment in time. Take the Tom Glavine card, for instance. It’s technically his "Diamond King Rookie," and while his standard 1988 Donruss rookie card is the one people hunt for, the DK version has a much more regal feel. It’s Glavine before the Cy Youngs, before the 300 wins, rendered in vibrant watercolors.
The Most Notable Cards in the 1988 Set
If you're digging through a shoebox of these, there are a few specific cards that still carry some weight, mostly for nostalgia or PSA registry collectors.
The Nolan Ryan Diamond King (#1) is the big one. It’s the first card in the set. Because it was on the top of many stacks, finding one with perfect centering and no "snow" (those annoying white print dots) is surprisingly hard. Ryan was with the Astros at the time, and the painting captures that sunset-jersey era perfectly.
Then you have Mark McGwire (#3). This was right after his record-breaking 49-home run rookie season. In 1988, this was the card to have. If you pulled the McGwire DK, you were the king of the playground. Period.

Other heavy hitters in the subset include:
- George Brett (#14): A classic depiction of the Royals legend.
- Kirby Puckett (#12): Coming off the 1987 World Series win, Puckett was a god in Minnesota.
- Don Mattingly (#7): "Donnie Baseball" in his prime. The Yankee faithful still pay a premium for high-grade copies of this.
Why "Junk Wax" Doesn't Mean "Trash"
People love to bash the late 80s. They call it the "Junk Wax Era" because the supply was infinite. And yeah, from an investment standpoint, 1988 Donruss is a bit of a disaster. You can buy a factory set for less than the price of a decent lunch.
But value is subjective.
The 1988 Donruss Diamond Kings represent the last gasp of baseball cards as a hobby for kids before it became a playground for high-end speculators. There’s a texture to these cards. The canvas-stock feel of the paper, the specific smell of the 80s cardboard—it’s a time machine.
Also, let’s talk about the errors. 1988 Donruss is riddled with them. The most famous isn’t in the Diamond Kings subset (it’s the Stan Musial "Puzzle" error or the various Bill Madlock iterations), but the DKs weren't immune to the quality control chaos of the time. You’ll find variations with missing periods in the "Inc." on the back or slight color shifts that make Perez’s art look like a psychedelic trip.
Grading the 1988 Diamond Kings: Is it Worth It?
This is where things get tricky. Should you send a 1988 Diamond King to PSA or SGC?

Usually, no.
Unless the card is visually perfect. We’re talking 50/50 centering, razor-sharp corners, and a surface free of those tiny wax stains. A PSA 10 Nolan Ryan Diamond King can actually fetch a couple hundred dollars. Why? Because the population is surprisingly low. Out of the thousands of copies submitted, only a fraction get the "Gem Mint" label. The blue borders show every single flaw. If a card rubbed against the inside of the pack for thirty years, it’s probably a PSA 8 at best.
If you have a childhood favorite, maybe send it in for a "Slab" just to preserve the memory. But don't expect to retire on it.
The Checklist Complexity
The 1988 set was huge—660 cards plus various subsets. The Diamond Kings occupied the first 26 slots. But Donruss also included "Bonus" Diamond Kings in certain packs. They were trying to create scarcity in a market that didn't have any.
Wait, did I mention the puzzles? Instead of a piece of gum that tasted like pink drywall, Donruss gave you three-piece puzzle strips. In 1988, the puzzle was Stan Musial. To get the full "The Man" portrait, you had to collect all 63 pieces. The Diamond Kings and the Musial puzzle were the "prestige" elements of a brand that was otherwise fighting for its life against the juggernaut that was Topps.
Technical Specs for the Nerds
For those who care about the nitty-gritty, the cards measure the standard $2.5 \times 3.5$ inches. The stock is a clay-coated paper that’s thinner than what we see in modern products like Topps Chrome. The back of the cards featured a short blurb about why the player was chosen as a "King," along with their career stats.

Interestingly, the Diamond Kings were also sold as a separate "Jumbo" set. These $5 \times 7$ versions are actually much rarer than the standard cards, though the demand is lower because they don't fit in standard binders. If you find a 1988 Jumbo Diamond King set in the wild, grab it. It’s a cool piece of history that most people overlook.
How to Handle Your 1988 Collection Today
If you just found a stack of these in your parents' attic, here’s the reality check.
First, stop touching the edges. The ink used for the 1988 blue borders is incredibly brittle. Second, check the centering. 1988 Donruss was notorious for "diamond cuts" where the image is tilted. If your McGwire or Ryan is tilted, it’s basically a common card.
Don't bother looking for "short prints" in the Diamond Kings subset. They were printed on the same sheets as the regular commons. The "scarcity" was an illusion created by the fact that they were at the front of the checklist.
Actionable Steps for Collectors
If you want to dive back into the world of 1988 Donruss Diamond Kings, don't go in looking for a profit. Go in for the hunt.
- Buy a Sealed Box: You can still find 1988 Donruss wax boxes for $30 to $50. It’s the cheapest way to experience the hobby as it was in 1988. The thrill of hunting for a Gem Mint Nolan Ryan is worth the price of admission.
- Focus on the "Jumbo" Versions: As mentioned, these are underrated. A full set of 1988 Jumbo Diamond Kings looks incredible framed on a wall.
- The Perez-Steele Connection: Look into Dick Perez’s other work. Understanding his influence on sports art makes the Diamond Kings feel more like "mini-masterpieces" and less like mass-produced cardboard.
- Registry Sets: If you’re a competitive person, try building a PSA 9 or 10 "Master Set" of the 26 Diamond Kings. It’s a challenging, yet affordable, goal that will actually result in a collection that holds some value over time.
The 1988 Donruss Diamond Kings aren't going to pay for your kid's college tuition. They aren't the 1952 Mickey Mantle. But they are a vibrant, painted history of a transitional year in baseball. They are the bridge between the old school and the modern era. And honestly? They just look cool. Sometimes, that’s enough.
Next Steps for Your Collection:
Start by auditing any 1988 cards you already own for "corner whitening" and centering. If you have any that look perfect, compare them against high-resolution scans on the PSA or SGC websites to see if they're worth the grading fee. If not, pick up a "Monster Box" of 1988 Donruss from a local card show—it's the best $10 you'll ever spend on nostalgia.
