Castle Milk Chocolate Casino Chips were recently launched in the USA. They come in mesh bags weighing 50g and containing 10 milk chocolate chips.
When I was a kid, we had the typical chocolate coins. But at least with these chocolate poker chips, I suppose you could actually use them to play poker with, and possibly eat your opponents out of the game (while they're not looking!)
