TMabry9433, to the forum. I'm not one of the experts here,but one should be by shortly. In the mean time have a look at VAM-18A http://www.vamworld.com/1880-P%20VAM-18A and see if it's close. BTW.Very good photo's!
I think the difference between the 18 and 18A, is the 18A is the later, "clashed" die state.As is Your coin is.Where as the 18 does not have clashing marks. But again I'm no expert.So we'll wait for one. Oh yeah,nice coin.
