The guy I bought them from would go to storage unit auctions over the yeas and when he would get a key he would hang it on the key hook that he gave me with the keys. The chips went into a box. So that explains the randomness. Here is a picture of the key hook. He has a permeant spot at the flea market and says he will keep a eye out for casino stuff. We had a great time looking at all the other stuff he has, always nice to make a new friend!
