I am looking for some resources to help me start grading my swiss collection (20th century). If anyone is aware of any books or websites with discriptions or pictures that might help (other than general grading standards), please let me know. Thanks.
I typically go with the book which is entitled "Blackbook Price Guide to World Coins" (2009) version is what I have. I know they have a section on Switzerland, so it might be of help.
