I just received this nice Aurelian tetradrachm in the mail. What's interesting about it is the silvering that remains. I have quite a few nice tetradrachms from this period but this is the first retaining significant silvering... I guess I didn't realize that it was applied to tetradrachms. Does anyone know more about the when these were "silvered" and when they were just base metal without a silver wash? Show your silver/tin washed tetradrachms if you'd like! Aurelian - LE (Year 5) - Emmett 3924?, Milne 4422? PS: Also I was hoping I could get a reference check on this one from someone who may have Emmett or Milne... on acsearch there are varying attributions for the same coin.
