I think the $15 price tag for you to purchase is very good. I sold a couple dozen last year and while a few went for as little as $15 (like generic ones that just said "Bally"), most were a bit more expensive. The belly glass that had a club name with a nice logo went for the most.

The average price was about $30. The favorite (most bids) was the King's Castle with cartoon-style log. I think it went for $58. My own belief is that there are a lot fewer old pieces (especially clubs from Elko, Winnemucca, etc.) of belly glass than there are chips or dice. Many clubs only had a couple hundred slots. AL
