I haven't seen this chip before. I found some chips from this place in Sacramento (dimes and $1) some time ago and I thought they were from Sacramento - that is what the guy selling them said. He wasn't a chip collector so perhaps he was guessing as well. It is interesting that the $5 chip has inserts but that the $20 doesn't. In any case it is a great looking chip - thanks for sharing. (the blue in the scan is from my old scanner - not on the chip)
