Re “Hi! I'm new to marble collecting, as far as identification is concerned. Can you recommend a good resource for me?”
Marian, if you’re looking for a good book or two on the subject I’d recommend American Machine Made Marbles by Dean Six (and others) and Marble Mania by Stanley Block as good places to start - both have lots of pictures and are still pretty relevant, though machine made information especially is constantly being updated as we all learn more of our past.
For website links - besides this great board source here, of course - I’d highly recommend marblealan.com, and glasmurmeln.com. The latter site is operated by one of this board’s members, marbleconnoisseur, and has some excellent info as well as pictures of some of the world’s most beautiful marbles.
My other recommendation is to find the next marble show nearest you and go, preferably a day or two early, and you’ll learn more there in a short period of time than you’d believe possible. It’s getting harder to find a comprehensive list of such shows, but here’s a link you can check: http://www.kingofalltechnology.com/marbleshows.htm
If you’re interested and you care to share what area of the country live in I’m sure we can find an appropriate show for you. It’s well worth if you’re serious about collecting.
Good luck! It’s a fun hobby, with lots of fine folks, always something to learn, and best of all - beautiful marbles to discover.
