There are two publications that might be of interest to the club that I can think of.

One is the C.A.T.C. Canadian Association of Token Collectors which puts out a quarterly publication
for it's members .... likely inexpensive and these people are already collectors in a similar field.

Another Publication would be NATCA which publishes a monthly Newsletter also to token and exonumia
collectors. This add would not be a huge expense either.

I could look into it more if the club BOD has any interest in either of these.
