Nice coin. Unfortunately this is what I was talking about, there are highlights and shadows that do not match the expected height for things, and no easy way (that I know of) to make that into a 3D object, but someone else may know a trick.
I would maybe look at other options ?
- Photo V-carving it ? (If you have Vectric VCarve that is…)
- Make it a lithophane
- trace it in Inkscape and engrave this with a diamond drag bit on metal? It’s not going to be fun though, here’s the (poor) result that I got playing around for a few minutes, Inkscape gurus may be able to do much better
