Ramsay Stack and Cylinder sets are available in many different coin denominations. The coins in each set are soldered together and hollowed out to hold a cork, or other object. I even bore a recess into the bottom of the top coin to give more depth for the load. Each set includes a Leather cylinder, Solid Coin Stack & 2 Corks. The CSS is a Kueppers innovation and is a tube that fits inside the cylinder during storage and travel to prevent it from collapsing. It is important that the cylinder remains round so it nests and denests from the stack with ease and without hanging up.
