The Proof 1907 Liberty Had Nickel has the smallest mintage of any date in the entire series, but it remains a common coin since most of the original 1,475 Proofs still exist. The most frequently seen grade is PR64, and anything above PR65 is scarce to rare. Cameo examples are scarce and represent 15-20% of the total population. Deep Cameo examples of this date have not been discovered and may not exist at all.
