As I recall, I've only seen this numeral font on Chips from Cuba. They all look like they were made of the same material. Does anyone have this font on a US chip? My guess is that there was a chip maker in Cuba that used this font exclusively. I just picked up some chips that were numbers on both sides... I'm guessing they were made in Cuba. Anyone have any input to share? Chip pics are from the guide.

Some chips below I just picked up... the same font as above.
