With the S denoting that this variety of Buffalo nickel was struck at the San Francisco Mint (and only 970,000 were minted, with other mints producing millions of examples by comparison), finding one of these coins in mint condition could fetch you a princely sum. According to the Professional Coin Grading Service (PCGS), a particularly impressive example of this coin (graded MS66 by competing grading service Numismatic Guaranty Corporation or NGC) sold at a 2008 Bowers and Merena auction for $322,000. 1867 is a key date for shield nickels, which were minted from 1866 to 1883, but when the 1867 coin was set to be issued, a variety of rays surrounding the numeral five on the reverse were to be removed.
