After a long shipping period and an even longer battle to get the post to actually deliver my mail, I have this coin and a sister coin in my hands:

The coin on the right I got for a little cheaper than the first, simply because it was cheap and I plan to flip it.
I did notice that in addition to the slight portrait differences, the monograms on the reverse are different. Are these mintmarks? Assayer's or mint-master's initials?
