Classic 3D Coin Design Needed

I’m commissioning a fully-modelled, classic-style coin that will ultimately be struck in metal. The aesthetic must feel traditional—think timeless relief depth, crisp edges and balanced symmetry—while still allowing room for a touch of creativity.

Here’s what I already have for you:
• Reference sample photos for the obverse portraits.
• The exact short motto that must appear as an inscription.
• Dimensional specs (diameter, thickness, relief height) straight from the mint.

What I need from you:
1. A sculpted 3D model that faithfully integrates my portraits and text, arranged in a harmonious classic layout.
2. Production-ready files (STL or OBJ) with clean manifolds and proper relief depths, ready for CNC or laser engraving.
3. A couple of beauty renders so I can preview finishes before minting.

We can iterate together—I’ll review low-res drafts, mark-up any changes, then sign off on the final high-res file. If you normally work only in 2D, this project isn’t a match; I do require true 3-dimensional sculpting skills in tools such as ZBrush, Blender, or similar.

Once you’re confident you can capture that timeless coin feel while meeting manufacturing standards, send over a brief note on your approach and a link to comparable coin or medal work.
