Half dollar (United States coin) -- The half dollar, sometimes referred to as the half for short, is a United States coin worth 50 cents, one-half of a dollar, and is the largest United States circulating coin currently produced in both size and weight, being 1.205 inches (30.61 mm) in diameter and .085 inches (2.15 mm) in thickness, and is twice the weight of the quarter. The current half dollar, the Kennedy half dollar, depicts the profile of President John F.
