I’m not an expert grader, but for these hammered/milled crossover-era crowns I tend to look at (1) the high-point wear on the portrait and shields, (2) any edge issues (nicks, filing, mounting traces), and (3) whether the surfaces look cleaned/tooled.
If you can post a couple more close-ups (obv/rev + edge) under consistent light, it’s much easier to judge detail vs. surface problems. Also worth keeping in mind that even a lower numeric grade can still carry a premium well above melt if it’s problem‑free and attractive.
For a quick rough baseline on the silver content/melt value (just to separate “metal floor” from numismatic premium), this calculator can help: https://mygoldcalc.com
