This is a full set of the universal double sided folding and reducing dies ranging from .7" to 1.6" openings at 17 degrees for optimal folding and reducing. These dies can be used in conjunction with the stabilizer folding cones and mandrels to fold U.S. dime to Silver Eagle sized coins leaving no mark on the inside of the coin. This die can also be used to fold and reduce similar sized coins for final sizing of coin rings. These dies can be used in conjunction with each other to pretty much fold and reduce all coins :) *The coins pictured are not included* Copy and paste this address into your internet browser address bar to see a youtube video using a die: https://www.youtube.com/watch?v=lCwPbu1lGLY NOTE: A detailed description of the coin ring making process can be found in "How to Make Coin Rings" training manual found here: https://jasons.works/product/coin-ring-tools-training-manual/
