Okay, that sounds great! I'll definitely try to find that book. In the meantime, I want to try to sort these out the best I can to where all the duplicates are together. It looks like there are sometimes marks to the left and right of the monogram and again on either side of the castle. Is the placement of those marks consistent such that the mark to the left of either is always a mint mark and the mark to the right is the designer?
