1991 Topps Traded Baseball Forum

I thought I was doing good sorting out white and gray backs. Now I see there is a tiffany also. Are those white baacks also and if so how do you tell which is which?

Yes they're white stock as well. Tiffany has the usual super glossy front so I would say if your white backs are not noticeably glossier than your grey backs then they are not Tiffany. 
 

As often as it is asked online we should pool a stack of Tiffany commons to mail to people as a service because once you hold one in hand it is extremely obvious lol

for some reason Tiffany reminds me of "Albino". lol lol

Tiffany has a glossy finish similar to the All-Star and Rookie inserts Topps had in the 80s and early 90s, and IIRC the Traded sets have gray backs in packs and white in the small boxed sets.

Thanks for the help
