2004 Donruss Playoff National Cleveland Browns Football Forum

I have a complete 6-card set as pictured in the DB.  However, I have an additional 6-card set of identical cards where each has a gold foil stamp of a guitar neck with 2006 National Cleveland on it (the foil stamps are identical to the one on the no-number Promo: https://www.tradingcarddb.com/ViewCard.cfm/sid/122865/cid/10258848/2004-Donruss-Playoff-National-Cleveland-Browns-NNO-Kellen-Winslow-Jr.).  The gold foil stamp is in an inconsistent location and actually blocks part of the name on several cards.  Is this a variation that should be recorded here?  As I said, I have a complete set of 6 both with and without the foil logo...

Probably stamped on site at the show. I used to have dozens of cards stamped or embossed at the different nationals I attended, for opening packs at the Pacific booth or whatever. 

Or I could be totally wrong as usual. 

I agree with switzr. You could have just about anything stamped. Really no different then having a card autographed. Aftermarket alterations aren't listed in the database.
