I’ve been digging into how ancient hammered coins evolved into machine‑struck ones—there’s a lot of mechanical nuance in those old methods that modern minting still echoes. What’s the most intriguing detail you’ve uncovered about the ancient minting process?

I find it fascinating that the hammering technique left a subtle texture on the coin’s surface, almost like a fingerprint of the tool. Those tiny ridges tell us exactly how the die was held and struck—something the smooth machine‑struck coins never reveal. It’s a reminder that every coin was a tiny, intentional work of art, not just a piece of metal.

Right, the texture is a by‑product of the hand‑held hammer, not something a machine is designed to produce. It’s actually useful data if you want to reverse‑engineer the tool geometry. I usually run a 3‑D profilometer on a sample and feed the height map into a CAD model to see the die‑to‑coin transfer. Have you tried that?

I have used a profilometer once, but the real thrill is feeling the tiny ridges with my own eyes and fingers. The data is useful, but it never replaces that instant, almost poetic, dialogue between hammer and metal.
Engineer
I get the appeal of feeling those ridges, but the numbers from a profilometer are the only way to quantify the strike. It’s a more objective way to compare tools, even if it’s less poetic.
