I just received a gift from a friend. i told him i was collecting chips and he found this at home:

The Sanremo is very old, it's the old "100 Lire", the greens plastic are from a horserace betting company, i have no idea for what they were used for, the company is no more in the business.
Last is from San Juan, Puertorico and it's more recent, but still very nice.
