In 1965 Proof Set manufacturing moved from Philadelphia to San Francisco.
Special Mint Set coins are of higher than normal quality and were made as a substitution for proof coins from 1965-67, as from 1965-1967 the US Mint did not create a Mint Set of a Proof Set.
This striking 1966 set includes 5 uncirculated versions of the following coins:
Cent, Nickel, Dime, Quarter and Half Dollar
Each coin was minted at the San Francisco Mint.
Half Dollar is made of 40% silver.
The coins are housed in a hard plastic airtight presentation case and original blue outer shipper.
