Best Horsea Cards to Grade

How to read the Horsea ranking

Every Horsea card listed here clears one bar: its PSA 10 price beats its raw price by more than the cost of grading it. 2 Horsea printings pass. 2 of them (100%) have a gem-rate sample of at least ten graded copies in the population reports, and 1 of those keeps a positive expected value once every grade outcome is weighted by how often the card actually receives it.

The order is expected profit, not the PSA 10 best case, which rewards the widest raw-to-gem gap whether the card gems one time in two or one in fifty. Here the top row, the Horsea from Aquapolis, gems 42.5% of the time across 73 graded copies: +$154 is what a long run of submissions would average, $441 is what one lucky copy returns.

The median gem rate across the sampled Horsea cards is 42.5%. Roughly one submitted copy in 2 came back PSA 10, and no row here covers raw price plus fee at PSA 9, so the gem rate decides whether a submission pays. Of the 2 ranked cards, 2 need a 10 to break even and 1 loses money on expectation. 1 rests on a hundred or more graded copies.

Before you submit a Horsea card

Grading pays on condition. The four things every grader scores — centering, corners, edges and surface — can be checked at home before paying a fee, and a copy that is visibly off-centre or has a whitened corner will not gem whatever the population says. Those gem rates come from a self-selected population of clean copies, so a random copy does worse.

The cost column assumes a PSA submission at the tier covering the card's PSA 10 value, fees as of 2026-09-26, and raw is CardTrack's blended near-mint price, not a sale of your copy: pay more, or hold a lighter copy, and the break-even moves against you. Test a card with your own numbers in the ROI calculator, see the printings that fail the bar on the Horsea card list, or see how gem-mint premiums run across the whole catalogue on the PSA premium index.
