1951-S "Sample" Lincoln Cent, Given By George B. Gillin, Superintendent Of The San Francisco Mint, To Those Who Visited The San Francisco Mint, In 1951. The uncirculated coin is taped to a lithographed souvenir card. This would be a nice addition to a display of Lincoln Cents. The fragile card is 5" by 4 1/4" in size, and has a small missing corner, two corner creases, and tape stains, yet displays well.
