Yin Yang Coins 1" (3 Pack) USGS

I was looking for a set of dedicated coins for divination using the I Ching, and these coins were designed for exactly that purpose. They even have the numerical values to calculate the lines, so they're more convenient to use than regular coins.

I use these for atmosphere in magic tricks. The Yin-Yang theme can be used in many tricks. Use them to allow spectator to mark selected stacks of cards. Or, put a prediction on the back of them using circular price tags, etc. etc. The coins are slightly larger than a US quarter. Pleased with this set.
