Regarding Alcoholics Anonymous tokens: I have collected these for years. I know of no book or catalog on the nature and variety of these tokens. Personally, I have attributed at least 20+ varieties (for each year of sobriety). If a book on the tokens is published, I'd sure like to find out about it.
It's getting harder and harder to find a subject area of numismatics that hasn't already been catalogued. Here's a chance for a researcher to make a mark!
