A proof coin will have mirror like fields (parts of the coin with no design) and an uncirculated coin will have shiny, but not mirror like fields. A proof coin is more expensive and would sell for around $70.
The "S" mintmark denotes this coin as a Proof coin. Unless it has been handled correctly it's only one cent. The Mint does not sell single one cent proof coins. If the coin is still in collectible condition, the value is about $2.00.
