NGC 1979 Kennedy half wrong planchet struck on SBA dollar blank.
The Kennedy half is struck on a Susan B. Anthony dollar blank, and weighs 8.1 grams, which is much less than the normal weight of a half dollar (at 11.34 grams.) The coin is missing some of the lettering and part of the date, since the SBA blank is smaller than that of a half dollar.
An affordable example for the type, with very pleasing surfaces.
MS64 lustrous and above average eye-appeal.
