The coins come in 10 different colors. I'll use the gold coins for effects like 3 Fly, Gadabout Coins, and one-coin Flurries. Then I'll use the green coins for Spellbound changes.
The colored foil is in 2 halves so it's easy to make a double-sided coin by carefully prying off the foil cover from one side of a coin and adding it to another coin. I'm using mine for Marion Boykin's Copper/Silver-Surprise! I'll produce a silver coin and turn it to green and back to silver several times then turn it to a gold coin. And of course, the gold coin is a great giveaway.
The chocolate coins are 10 cents each and are about the same diameter as an American half dollar, but thicker and much lighter. So some practice is definitely needed before you run out and perform with them. But you'll get the feel for them pretty quickly.
Magic and chocolate, what's not to love!?
