These sets were put together to commemorate the 40th Anniversary of the end of the 'Ike' Dollar series in 1978. These PCGS sets contain all 11 of the Proof coins issued during the series. Both the Silver and Clad Proofs are included. As most collectors know, toning is an issue with the Ike Proofs, but these are nice, toning-free coins in new PCGS holders. All grade PR69DCAM.
