I will admit that interest in varieties, except on some of the early US series was rather low except among a small number of serious specialists, and interest in errors other than some mild curiosity was pretty much non-esistant at the time. (errors were usually viewed as defective coins and practically worthless to the extent than precious metal coins would be scrapped, and base metal coins just tossed out in the trash. Active, though mild, interest in errors didn't really start to grow until the late 50's early 60's.
