1909 S/S Lincoln Cent Wheat Penny Value depends on if the coin is red- red and brown or brown, and in that order (Image examples below). An example in G4 (Good) is worth an average of $100 and an MS64 Red (Mint State) $775, and all other grade values will fall somewhere in between those two.
The S/S, but not the horizontal variety, and is more rare, but still an RPM or Repunched Mint Mark and is the result of the first S mint mark to be punched in the wrong orientation and then correct with another attempt in the correct position. (All mint marks where hand punched into the dies prior to 1990.)
