About the Nidoking card

About Nidoking in the Pokémon world
The Ground-Poison final form of the Nidoran♂ line. Tall bipedal silhouette with a long horn. Considered one of the strongest Ground types in Gen 1. Base Set holo Nidoking is a steady five-figure card in PSA 10 1st Edition. Quieter than the marquee starters but consistently in demand.
Print variants and how to spot them
Aquapolis shipped in Standard, Reverse Holo, and Crystal Type prints. Crystal Type cards are rare alternate-art holos with a colorless rainbow holofoil pattern, pulled at significantly lower rates than standard holos. They are the marquee chase for this set.
Grading and condition
For graded buyers, the holo window is where most grade points are won or lost. Surface scratches and print misregistration on the foil are common, and centering on Wizards-era holos was inconsistent enough that PSA 10s remain genuinely scarce a quarter century later. The PSA 9 to PSA 10 price gap on this kind of card is wide enough that pre-grading inspection under a loupe is well worth the time.
If you are buying this card
If you are buying this card, the order of operations is variant first, then condition. Verify the print variant (1st Edition stamp visible, drop shadow on the right edge if Unlimited) before you negotiate on price. For raw purchases above $500, insist on photo or video showing the holo surface under direct light from a 45-degree angle so you can spot hairlines. The "live market price" on this page tracks recent eBay sales, but the actual transaction price will vary by variant, grade, and how recently a comparable sale closed.
