I know exactly what you're talking about Dave. Some years back I taught an adult education-no credit course in leathercraft at San Diego City College, and I found that teaching is one of the best ways to learn. When you're teaching, or helping, someone else with less knowledge than you, you better your own knowledge.
I have guess-timated the grade on my coins, but I will continue to post coins here, and will look forward to the feedback concerning them. I'm satisfied that I have some of them right, but others.....
Thanks.
