The Aurelian reminds me of one of mine that almost looks like it had enough silver in the mix to look gray without plating. I wonder if they experimented with other answers to making coin more acceptable before necessity led to the silver washed XXI coins of Aurelian's reform.
Nice clean up job. Can you give us a hint of what processes you used and about how much time? Thanks.
