The San Francisco Mint pumped out 2,105,000 examples of the 1913 Type 1 Buffalo nickel, depicting an American bison standing upon a mound. While 1913-S Type 1 Buffalo nickels may boast a decent seven-figure mintage, the issue has a relatively small number of survivors, with perhaps only 10,000 extant across all grades. Examples are tough across the grading spectrum, though perhaps 10% of known specimens are available in Gem Uncirculated grades or better. Presently, the highest-grading specimens come in at MS68, though PCGS has certified just two at this level. That means many registry set collectors clamor for the few dozen or so MS67 specimens that trade in the marketplace from time to time.
