Hello thanks to all of you, indeed I have two auction houses interested in selling this collection one being Potter and Potter and the other one is Skinner Auctioneers but I've been getting more people talking me into Potter and Potter I suppose they have more expierience selling this kind of items. As far as proof as they were in the casino I have only letters from my great grand father talking several subjets regarding the casino business and the roulettes. As far as pictures go I will upload nice pictures os the chips next week so we can uploaded to the data base.
