Steve...I went through Salinas California (maybe 30 miles from Castroville) and found this one chip in an antique store there. I didn't see any other chips there. This chip looks almost unused. I think you are right about seeing a few on eBay....I remember seeing a couple, but don't remember which denominations. I know I don't have it for my collection, so I am happy with one. 😀 Thanks for your input.
