This incredible 1976-S clad proof bicentennial half is double-struck, with the strikes 5% and 15% off-center of each other. The coin is much larger than normal with a big expansion in size, which was caused by the coin being struck outside of the collar die, and so expanding far beyond its correct diameter.
Very dramatic looking, with the tops of Kennedy's head overlapping and two sets of the word "LIBERTY" on the obverse. On the reverse, the coin exhibits two sets of "HALF DOLLAR" and "PLURIBUS UNUM", and parts of "OF AMERICA" show strong overlapping.
A very rare double-strike, and with very good eye-appeal.
