These are the Key Dates 1979-S Type 1 . or Filled S  Proof Lincoln Cent.  This coins were removed by myself from its original Proof Sets with gloved hands using the utmost care.  These are beautiful coins with deep mirrors and ultra cameo contrast. You will also receive the 1979 P and D bright red gem business strikes   Any color you see is the reflection of my pink camera in the mirrored fields of the coin.  I have tried my best to capture the mint mark in the photos but my camera can be troublesome with small mint marks sometimes.
