Eli,
I got your sample file and here's what I did:
1. I used an Anything Grooves plane to do the displacement instead of a
cylinder.
2. On the Grooves UI I turned on Adaptive Mesh, Zero is empty and Smart
Split. I also set the U and V samples to 482 to match your image size.
If your full image is very big, this might not be an option.
3. For the displacement shader I used a Gradient under the curve filter
to crop the sides. I used a mixer between value = 1 and your texture to
control the relative depth of the engraving. More towards your texture
will make the engraving taller.
4. On the texture map I turned on Interpolate and Filtering = Summed
Area Table. This will help smooth the samples grooves takes from the shader.
5. The coin's shader, I used the same Gradient/Curve Filter in the alpha
channel. The only difference is that the curve is adjusted so that there
is no soft falloff.
This leaves an open back coin, but you can always build the other side
the same way and align them back to back.
