While up in Saratoga today, I came across a chip I hadn't seen before. It was a red/brown color with a web or weave mold (the same mold that is on my Piping Rock $25 chip) On one side there was a stamp that said $5.00. there is no stamp or design on the other side.

This was being sold with other Saratoga Chips. Anyone see this before? Any opinions as to where it is from?
