I’ve posted all the pertinent info in my User Profile. If you’re interested, post or PM a guess. I haven’t started yet, and I’ll have limited time in the coming week, so it might be as long as a month before I finish counting, as I’m doing it all by hand. If you need any clarifications, feel free to ask.
So. . . two things you can guess on. The weight and/or the total number of coins.
