Fleer Ultra Platinum Medallion

[tmoore_25]

I was looking at purchasing some of these and noticed that some are numbered /50 and some are not numbered. Are the non-numbered ones backdoored or was there some kind of mistake made when these were printed. I was on a hiatus from about 1995 - 2005 and am trying to get back into that era, but admittedly am lacking knowledge from those years.

Edit: I was specifically looking at 2005 Fleer Ultra Platinum Medallion Tom Glavine. There is a PSA 9 that is numbered and I see some raw that are not numbered.
