Size 11, made from a 1943 Liberty Walking Half Dollar. 3/8" wide. 90% silver, contains about $27 worth of silver bullion. Chosen to specifically show off the year, the word LIBERTY, IN GOD WE TRUST, and Victory's face and outstretched hand. And the sun! So poignant! Using what was available, and this was the only silver available in most cases - coin silver.
