Great Question!
Im looking for the same info. I know there is one albeit not very good video on YouTube on it.
I'M from Canada, and the Canadian numismatic society also offers a course. It Is only 2 books but is significantly cheaper.
The downside is that is would be more focused on Canada. I've not done either but plan on doing one over the summer.
Im also Curious to see what other people have to say.
