Jaime Hernandez: This is the first year that the Kennedy Half Dollar was struck in Copper Nickel Clad, as the Mint completely removed the silver composition from Kennedy Half Dollars this year.
The 1971-P Kennedy Half Dollar is common in most grades up to MS64 condition. In MS65, they become a bit difficult to find. In MS66 gcondition they are now scarce with possibly 200 or less examples surviving in this grade. In MS67, they are very scarce with less than 10 examples known and none being higher.
