I just stumbled across a bunch of listings on Ebay of rare Las Vegas prototype chips.
I have been out of town for 2 weeks and I don't know if these chips have been discussed on the Chip Board.

I don't know if anything about these chips on Ebay listed by seller - BEACHGUY805 - has been posted here.
A lot of rare prototype Las Vegas chips that were given to the seller 30 years ago by Paul Endy of Paulson.

Bob H. - There are a bunch of Boxing Prototypes listed by this seller.

Take care,
Jerry
