So Colin, to continue (just let me know if you get bored!), what makes a mis-strike / defect / weak strike of interest?
For example, you have on your site an 1862 with RFG instead of REG. Is this cause by a filled / clogged die, or the wrong letter on the die? Why is it important? When I look at my 1862, I'm (mostly) missing the top of the first T in BRITT, part of the C in VICTORIA and it has only one stop in the colon after the D in F:D: Is any of that significant?
