I was wondering why my searches I run on didn't pick up your chips and I noticed that you have them listed in the Collectibles & Art > Coins & Paper Money > Bullion > Silver > Coins category so you are missing the target audience who buys these items. If you had not made this post on the chipboard, I would have never seen your auctions. There is a category specifically for casino chips with several subcategories which roll up into it and it is Collectibles & Art > Collectibles > Casino > Chips which would allow you to reach your target audience.

Anyway, very nice chips you are selling! All the best!
