1915-S Lincoln Cent. MS-64 RD (PCGS). Golden-brown surfaces are a bit bolder with more of a mottled distribution to the color on the reverse. Underlying pinkish-orange color shines forth nicely from both sides as the coin dips into a light. Scarce Choice Mint State quality for this semi-key date Lincoln cent issue with a relatively limited mintage of 4,833,000 coins.
