These coins cannot be used for palming in a stack because every coin has a rough burred edge on one
side that makes them not slide off a stack. That being said, I bought a bunch of them and glued them
together as double thick coins, with the burred edge on the inside and smooth side on the outside.
These turned out to work well for the “Charming Chinese Challenge” trick.
However, they are way
overpriced for these cheaply and badly made coins. Don’t buy them if you want to use them as super
thin palming coins.
