I got some of these GG's in a lot a while back. I asked the seller some specific questions about what she knew about where the chips came from... This is some of what she said...

"My Dad dealt cards (Blackjack) all around southern Indiana and probably into just adjoining states also. There were several illegal gambling houses in Bedford where he and my Mom lived. The only name I recognize is Dave Torphy. I have all Mom & Dads old pictures of that era, but none were written on, so have no idea about any of the specifics."

SHE MENTIONED DAVE TORPHY BECAUSE I ASKED IF SHE KEW ANY OF THE NAMES ON THE ORDER CARDS FOR SOME OF THE OTHER CHIPS...
This pic is some of the other chips she had in the same lot as the GG's.
