1977-D Kennedy Half Dollar--Struck on Scrap Planchet--MS-66 (PCGS). 7.96 grams. An unusual error offering. Apparently a piece of a clad planchet made its way into the coining dies and was struck as a 1977-D half dollar. Subsequently, it made its way out of the Mint in a bag and was later rescued by a collector. Most of these we have seen are either undated, or in relatively poor condition. This is certainly an exception and should be viewed closely by the perspective bidder. PCGS# E6732. NGC ID: 24UN.
