Poseidon
Poseidon ACEOs are a concentrated market. A handful of sellers own most of the listings, so the price you see is really their price. Breaking in takes a card that stands apart, not one that competes on volume.
Based on 19 priced listings.
The middle of the market. The median sits at $5. Price below $5 only to move fast; above $5 you need a clear reason (signed, OOAK, a known name).
Reading the Poseidon Market
Right now 6 sellers are listing, 83.3% of them with a single card up. The top seller holds 73.7% of what is listed.
The middle of the market sits at $5. Most cards list between $5 and $5. Over the last 59 days the typical price has been climbing, from $2.99 to $5. Price inside that band unless you have a clear reason to sit above it: signed, numbered, or a name collectors already chase.
Few listings are marked one of a kind, so leaning into originals is a real differentiator.
You will not win this one on price. Win it on the card.
