1883-O Show Pick

VAM-11 and 57 are of the same die pair, but when LVA listed the V57 it was for the beveled tail feather. Hard to tell by photos, but from what I can see it looks like it is a VAM-57. Die marker on OBV and MM of reverse confirm the dies anyways, so it is just a matter of die state. Your VAM-57A is later than the 57, which is later than the VAM-11, so the beveling should show on this coin to be a VAM-57. I have seen stages with very light beveling under the TF, but I still call them 57s..

Well it is a small beveling just below the rightmost tail feather. If no beveling, then yes it is a VAM-11... til things are straightened with LVA anyways. The beveling is pictured in one of the four plate photos on the VAM-57 page.

Yes, the die marker is present on the VAM-11 die state as well. It appears we need some LFCPs on the VAM-11 page. I didn't realize, or else that would have been fixed by now! The only real difference between feature-wise between the 11 and 57 is that tail feather, other than some 11s can come unclashed.
