So you’ve selected the coin that you’d like to make into a coin ring, you’ve annealed and center-punched a hole into it, and you’re ready to begin folding it down into a reduction die.
BEFORE doing so, you want to make sure that you protect the surfaces of your folding cones from premature wear and tear; and one of the BEST ways to do so is by beveling, or ROUNDING OUT the 90° edges on the top and bottom of the center-punched hole in your coin.
You can accomplish this process best by using a tool called a “deburring tool” that can be purchased online at Amazon.com for example for less than $10.00. One example of a deburring tool can be found below:
You grip the deburring tool in one hand and the coin in the other, and with nice and even strokes; begin to work your way around BOTH sides of the coin, keeping an even amount of pressure all the way around the hole.

Even after you’ve softened the inside edges of the hole in your coin by beveling, another trick to further lengthen the work-life of your folding cones is to START your first fold with something called a Stainless Steel “Starter Cone”, which helps to eliminate the perpendicular edge to the coin where it meets the surface of the folding cone, (which is at that point where the most amount of wear will occur to the surface of your folding cone(s). Another added benefit to deburring the hole is that you eliminate any micro-tears that may have been created by punching a hole.
If you own a set of my “Stabilizing” Reduction Dies, you’ll need to start the folding process with a Stainless Steel Starting Cone. The reason being is that there is not enough initial clearance for the folding cone to fit under the ram head and your coin prior to the folding process.
