Help with 2011 National Treasures Playoffs

[masteroftime]

Need help RE 2 different #20/#99 cards for same player-Ginobili.

Only difference I can see is the silver lettering on the front lower right.

Were there 2 different /#99 issues, one with silver and one without?


. Listed as 'National Treasures Playoff' - has silver stamped letters





. Listed on Ebay as 'National Treasures' #20/#99 - has only stamped letters - no silver

TCDB shows only '2010-11 Playoff National Treasures' with silver letters.
PSA pop report was no help. No joy with BO forum search.

Thanks for any help.
