Coins are generally Brilliant Gem Proofs being pretty much toning-free and spot-free although they may have a touch of Proof haze which is quite common with the older Proof coins. The original outside manilla flat pack and COA is included (provided one was issued). This is the only year that the Kennedy Proof Half Dollar did not bear the 'S' mint mark and the only year the Proof Kennedy Half Dollar was issued in 90% Silver composition.
