How to tell if 97-98 Autographics Century Marks are Fake?

[BobbyPhills13]

I've been doing a little research on 97-98 Skybox autographics Century Marks. I read on another message board that in the early 2000's Feer released all the surplus they had of cards, including Autographics Century Marks that were meant to be replacements. The autos are supposed to be legit, but they were un-numbered. People who then ended up with them started numbering the cards /100. Have any of you ever heard about this? Is there any way to tell a legit copy? Thanks

I posted both here and another community.

Real one has a stamp and words "century club" around the stamp.
Fake(rack pack version or the cards after fleer bankruptcy) does not have it.
Rack pack one only has a stamp without the words and the bankruptcy one does not have a stamp and the words.
