*This 1/4" - 3/8" folding cone is intended to be used as a replacement to your worn or damaged 3/8" phenolic or plastic folding cone.

This is the first cone in the set and is the one that used to take the greatest amount of wear and tear due to the center-punched coins' inner edge. That's no longer an issue with these new stainless steel cones!

Yet another improvement over all the softer folding cones made out of plastic, these new stabilizer folding cones are machined from wear-resistant hardened stainless steel, eliminating the need to purchase additional sets due to eventual wear-and-tear.

* The full set of 4 hardened Stainless Steel folding cones is recommended and can be seen in the link below:

The 1/4" - 3/8” size stabilizer folding cone is used in folding over quarter-sized coins, half dollar-sized coins, Morgan Dollar sized coins, and American Silver Eagle-sized coins. For example, this is the first cone that you would use when beginning to fold a Silver Eagle-sized coin that has a 5/8” inch (15.8mm) center hole punched into it; as well as a US Quarter-sized coin with a 3/8” inch (9.5mm) hole, or a 7/16” inch (11mm) sized center hole punched into it.

* This first folding cone in the Set can now begin to fold any size coin with as small as a 1/4" center-punched hole in it!


These Stabilizer Folding Cones are a more effective and efficient option than using the delrin bearing balls. Their design allows them to do a much better job of keeping the coin level as it’s being folded over into the reduction dies when using either a Ring Sizer Machine, an Arbor Press, or a Hydraulic Press.

To use, you simply set the coin level into your reduction die, insert an appropriate size folding cone into the beveled center punched hole, and then begin to press the coin down into the die. As you continue to fold your coin down into the reduction die, you simply switch to a SMALLER diameter-sized reduction die and a LARGER-sized cone (and the spacer provided if needed) to finish the coin’s folding-over process.

Below are recent reviews from clients:

--- "Quarter rings are my biggest sellers. I do large production runs of quarters, so I don't need a stuck coin slowing me down. And we all know how frustrating is can be to remove a stuck coin from one of the older cones. These are just what the doctor ordered."

--- "These cones are on another level. Just put plumbers tape on the cones so you don't ruin the inner detail and its golden."

* To use, simply wrap each stainless steel folding cone with pipe thread seal tape prior to the folding process to completely protect your coin rings' inner detail. (See the last listing photo for an example of a fully folded-over Morgan Silver Dollar made with these new cones showing the Teflon® pipe thread seal tape absorbing the metal-on-metal impact and protecting all of the inner detail.)

These new hardened stainless steel folding cones also work great with the “Stabilizer” Reduction Dies, as you end up having DOUBLE the stability of both the design of the die itself as well as the folding cone when folding over any US Quarter, US Half Dollar, Morgan/Peace Dollar, or the American Silver Eagle!

You don’t need to memorize which particular size folding cone fits into which size center hole in whichever coin you are about to begin folding over. Instead, you want to pick the Folding Cone that fits into your coin’s center hole, that will also fit under the ram head on your Ring Sizing Machine, arbor or hydraulic press.

As you continue to fold your coin down into the reduction die, you simply switch to a SMALLER diameter-sized reduction die and a LARGER-sized cone (and the spacer provided if needed) to finish the coin’s folding-over process.

--- CAUTION! These cones are small parts and can be considered a choking hazard. Please keep away from children and pets!
--- Always wear safety glasses.
--- Keep fingers, long hair, and loose clothing away from any pinch points or open flame.
--- Make sure to anneal, (heat, then quench) the coin often as you're working it often.
