Dinosaurs ACEOs are an open field right now. No single seller runs it and the supply is spread out, which leaves room for a newcomer to land and get noticed. Right now 46 sellers are listing, 67.4% of them with a single card up. The top seller holds 12.9% of what is listed.

The middle of the market sits at $7.75. Most cards list between $5 and $12.95. Over the last 14 days the typical price has held steady around $7.75. Price inside that band unless you have a clear reason to sit above it: signed, numbered, or a name collectors already chase.

Almost nobody signs their cards here, so a signature is an easy way to stand apart. Few listings are marked one of a kind, so leaning into originals is a real differentiator.

Open fields do not stay open. Plant your flag while there is room.
