Where can I learn from a book or videos to grade coins?
I'm gonna give you the flat answer, you can't. Books, pictures and videos are great once you already know how to do it. I like to think of it as me asking you to cook a 5* French meal when all you've ever made before is a Lean Cuisine. There's some middle ground you have to cover there.
the opportunities to acquire are mainly sight unseen
I'm assuming you mean not having seen it in hand vs not having seen it at all (photos).
I had been using PHOROGRADE
Garbage. Hot steaming pile of garbage. I will never recommend photograde as a tool to learn grading because all it tells you to do is compare your coin to the one pictured and guesstimate. There are SO many points that can go wrong with that, it's just not worth your time.
I learned to grade from CCF, and the way I learned was by asking the right questions with the wrong answers. If you post a coin and ask for a grade, don't accept the grades given at face value. Ask why it gets the grade that it does and not a grade 1 value higher or lower. Look at coins in hand and compare them that way. The last time I crash coursed someone in grading it took around 6 hours. They new almost nothing at the start and at the end they could grade decently well. I'm proud to say I still have room to improve, I suck at grading Indian cents
. Can't grade a circulated one worth a crap, but I'm learning and making an effort to learn.
I collect nickels and one site on the FS really helpe
Link? I'm gather material for another sort of forum article I'm writing and would like to see this site as it pertains to the topic of the article.
