Lets remember our boys and girls in Uniform! Lets take either the Nickel or dime and change them up. Maybe have a common obverse design similar to the SLQ and have a single reverse for each year.
For starters I can suggest Lake Erie, Bunker Hill, Santiago, Manila Bay, Ypres, Pearl Harbor, Battle of the Bulge, Chosin, Khe Sanh, Lebanon, Grenada, USS Cole, 9/11, Fallujah, and Mazar-i Sharif just to name a few.
This has the potential to create some beautiful designs and possibly educate people in some less known eras in U.S. history!
