Modern so-called dollar (1981) commemorating the 100th anniversary of the American Water Works Association. The piece is in silver and is about 38mm. Clean water (and water availability in general) continues to be an international issue.... look no further than Flint Michigan or at the drought we are having out here in California.

This association has an interesting website at: http://www.awwa.org
