Five copies of the same card, five different prices
We hold five slabs of Mega Dragonite Ex #271. Same card, same set, same year — and they are not interchangeable. Here is what separates them.
Open the Collect Shop and search for Mega Dragonite Ex #271 and you get five results, not one. That is not a bug in the grid, and it is not five listings of the same object. They are five distinct objects, and the certification number is the only thing that tells them apart reliably.
Four of the five are CGC 10. The label underneath differs: two read PRISTINE, two read GEM MINT. Both are tens. The qualifier describes how the grader arrived at the ten — a pristine ten has to be clean on all four subgrades, a gem mint ten does not. Collectors who care about that difference pay for it, and collectors who do not, should not.
The prices reflect that, and they are not tidy. As of today the five sit at $210, $200, $200, $189 and $185. The spread between the cheapest and the most expensive copy is $25 — about 13% — on cards that share a title, a set and a number.
This is exactly why the storefront keys on the certification number rather than the title, and why the grid does not collapse duplicates. Collapsing them would let you buy "a Mega Dragonite #271" without knowing which one arrived, and the one that arrived would be whichever we felt like sending. That is a returns problem waiting to happen.
Every card page links to the other copies for the same reason. If you are about to pay $210, you should be able to see in one click that we are also holding one at $185, and decide for yourself whether the label is worth the difference.
