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.
