It has the Birmingham assay stamp, the crown and 18 stamps for gold, and it also has the circular "m" stamp that indicates it was made in 1886 (not in the photos). For whatever reason, that's near the top of the ring. However, it also has this other stamp, and I can't seem to figure out what it is. Was it a mistake? It almost looks like half of a stamp, but I don't understand how something like that happens. I looks like it could be half of an "m" stamp or maybe an "r." I suppose it could also be a maker's mark, but there's already one of those to the very left. It actually looks like it was gouged to me or something, but even if it was supposed to be a date mark, the outline doesn't seem match the corresponding dates for the "m" or "r" letters (e.g., it's not an oval for the "m"). I also don't think the ring was ever resized because there is no evidence of a seam whatsoever, and I don't know why they'd ever cut it at an angle like that if it was. Anyway, I think I've made this post long enough. I'd just like to know what others think. The first photo is of the mark, and the second photo has some other marks. I tried to make them as good of quality as I could, but they are extremely small.
