Is there a resource out there to see

If a card in a set (on the checklist anyway) was ever actually produced/released?

Beyond a notation in one of the annual price guides (Beckett, Standard Catalog, etc.), I would say it's a case-by-case basis where you need to research the particular card in question.

What is the card?

I still have never seen the card in my sig line show up anywhere .. the Gold version does from time to time but never the base version...

Edited to add .. and none in the pop reports either
