$8-10 would be about right for the well worn and overcleaned chip in the auction. You should be able to find them nicer for $25-30 though. Remember there are two versions with different size printing on the inlay. The Light/Dark camel is not a good way to tell them apart, though.

Try to find them in close to this condition with lots of surface texture left:

Thanks Don!

My selection in chips here in west central Nebraska is limited, unless I use an online auction/store. That being said the gentleman who owns this chip would like to trade for a few circulated silver coins. I may go ahead and do it, this chip would be a good filler until I can hunt down a better example!

Cheers!
