Here's an interesting matchplay from Quepos, Costa Rica.

It's made of a thin plastic not much thicker then a peice of paper. It looks like a chip, and is round like a chip. Very clever. I don't know if they had someone actually cutting these out after they were made or what, but it's the first time I ever saw a match play coupon presented this way. The matchplay coupon is two sided, with the other side having the same graphics but with the value of 20.

Gallo has a couple of casinos (Casinos Byblo and Casino Kamuk) in Quepos, C.R., both using the same chips. Here are a couple of real chips from there. The front and back of the chips are shown. I have traders of the $1.00 chip, but not the 1,00 colones chip
