There are 2075 graded examples of the 1992 Donruss Rookies Pedro Martinez card, yet only 275 of those have graded out as a PSA 10 Gem Mint. There are 1295 PSA 9 examples, which is why that’s what you’ll much more commonly find for sale.
As a serious Pedro Martinez collector, you’ll most likely want the PSA 10. In late 2019, you can find PSA 9 copies for about $15-20, but the PSA 10 copies tend to be $30 or more. You’ll find a similar case for Pedro’s former teammate, Manny Ramirez, who actually has a whopping 2500 graded examples of his card in the set, yet only 270 graded PSA 10. That card, interestingly has similar price points. So, it’s pretty cool to have these two in the same set.
Of course, this card also depicts Pedro on the mound. Many of his early cards do not. I’ve also always preferred rookie cards with players in Major League uniforms, which is something I know many collectors prefer. All in all, this is a pretty nice and affordable Pedro Martinez rookie card that still holds some value from the Junk Wax era when graded PSA 9 or better.
