I do believe there is enough wear to keep the coin under an AU grade. There is also not enough luster still present to take the coin above an XF grade.
How long did it take to pull out a $1000 in ém? I say good deal. 40% silver is a pain in the ass for any industry associated with silver.
I think most of them look AU and I don't see any signs of harsh cleaning...but some of them do have quite a few marks on them. gatzdon, in order to see the mint luster, you don't need to put your coins under a stereoscope, just hold one and roll it in your hand in the light.
