1971-D Kennedy Half Dollar--Struck on a 40% Silver Planchet--AU-58 (PCGS). 11.59 grams. This exciting offering is for a 1971-D Kennedy half dollar - an issue that was produced using the then new copper-nickel clad composition - struck on a 40% silver planchet in error. As the Denver Mint used that composition for its 1970-D half dollar issue (distributed only in Mint sets), this planchet was obviously leftover from the preceding years coinage. Boldly struck with satiny luster, both sides exhibit only the lightest suggestions of toning to otherwise silver-gray surfaces. Exceedingly rare, and of great significance to advanced Mint error enthusiasts.<p>This lot is accompanied by a custom plastic holder for the coin, on the front of which is printed in gold lettering GEO.
