I have what I believe is an alcoholics anonymous coin. On one side is the AA serenity prayer. On the other side It says "easy does it" and "one day at a time" which I believe is affiliated with AA. This next part is the part that throws me off.. Along with the two sayings are the letters n h a inside a shape. Can some help me figure out the significance of this AA coin? I understand what my other AA coins mean because they have month and year counts, but this one I cannot find anything on.
