1965 Special Mint Set containing 5 coins - the Lincoln penny, Jefferson nickel, Roosevelt dime, Washington quarter, and Kennedy half dollar.

These coins were specially produced at the San Francisco Mint in 1965 with a proof-like finish. 

While not full proof coins, the SMS process gave the coins mirrored fields and frosted devices similar to proof coinage.

I am the original owner of these coins so it

comes with original treasury envelope.
