Tips for protecting your coin ring’s detail while forging it

What’s the best way to protect the inner and outer detail of my coin while I’m making it into a coin ring?

This is a question that I recently received from a customer of mine. There are some simple ways to protect your coin ring’s inner and outer detail while you’re forging it. In my own practice, I have 3 different tools that I can use when initially folding over, expanding, and then reducing the coin into a reduction die for final shaping:

1. A Ring Sizing Machine
This is my personal favorite.

2. A 1-ton Arbor Press

3. A 12-ton Shop Press (this is definitely way more press than you will ever need to use to make a coin ring; as you can easily use the 6-ton “A-frame” tabletop shop press from Harbor Freight if you want to).

The best way to protect the inner detail of the coin as you begin to fold it down into your reduction die is to use the New and Improved Folding Cones. This method of folding leaves no marks, scratches, or marring, thus preserving 100% of the detail on the inside of the coin. (See photos below for reference):

The key to protecting the outer edges of the coin ring as you’re reducing it is to use some impact-resistant plastic tape, which works very well in that it provides a buffer between the edge of the coin and either the ram head on your ring sizing machine, the press arm on a shop press, or the square ram on a 1-ton arbor press.

Below is a picture of my “Durston” Ring Sizing machine. Notice the thin grey layer of impact-resistant protective tape covering the ram head, (directly on top of the plastic bearing ball). This is what acts as a “buffer” and protects the outer edge of the coin that is facing UP from the reduction die as you are reducing it for shaping or final sizing of the coin ring.

The impact-resistant tape (shown by the red arrows below), is also great for covering the bare metal on the expanding splines of the ring-sizing machine. This acts as a barrier between the inner side of the coin that is making contact as you are expanding it down the splines; also leaving no marks, scratches, or marring; thus protecting the inner detail of the coin ring as a result. (See photo below:)

Below is an example of the crisp inner detail of a finished proof 1975 Half Dollar from the country of Belize that I recently made for a customer, using the impact-resistant tape and the plastic bearing balls.

If you use these simple tools, your coin rings will turn out with striking detail!
