Hello Don!

In many casinos on Spain the minimum in the American Roulette is 2,5 EUR and the 1,25 chip is used when you play 2,5 on the even chances ( Black, Red, Odd, Even.... ) and the O is coming and you lose the half of your bet.

In Casino de Barcelona the minimum on the Black Jack is 5 or 10 EUR, but not exist the 2,5 chip and they use two 1,25 chips.

Hope you understand my explanation , my english is not very good.
