Why This Page Exists
Checklists are built from what manufacturers announced, not from what came off the
presses. When a card ships with the wrong photograph or a name spelled wrong, there is no card number to
hang it on, so it never enters the catalogue. It exists in binders and nowhere else.
That makes errors the one corner of the hobby where an individual collector can
still add something to the record. Every card below is one held in this collection, described plainly, with
no claim about what it is worth.
Error Card FAQ
What counts as an error, and what it is worth.
What is an error card?
A card that left the factory with something wrong on it: the wrong photograph, a misspelled name, the wrong team, incorrect statistics, missing foil, a miscut, or an upside-down back. Some are caught and corrected mid-print, creating two versions of the same card; others run all the way through and are never acknowledged.
Are error cards worth more?
It depends entirely on whether anyone noticed. A famous, well-documented error on a famous player can carry a large premium. An obscure misprint on a role player usually carries none at all, because the market has no way to price something it has never seen listed. Scarcity alone is not value; scarcity plus demand is.
Why are error cards so hard to find in checklists?
Because checklists are built from manufacturer solicitations, not from what actually came out of the presses. Trading Card Database and Beckett catalogue what was announced. An unannounced misprint has no card number to hang on, so it simply does not appear. Errors surface through collectors posting them, which is exactly why a page like this one exists.
What is a corrected card?
When a manufacturer spots a mistake during a print run and fixes it, both versions ship. Collectors then distinguish the error version from the corrected version, and catalogues that do list them use suffixes such as 'a' and 'b'. The error is usually the scarcer of the two, though not always.
How do you prove a card is a genuine error and not damage?
Factory errors are systematic; damage is individual. A miscut that repeats across multiple copies came off the press that way. A single crumpled corner did not. The test is whether another copy exists with the same flaw in the same place, which is why documenting them publicly matters more than owning them.
