David Hall: In circulated grades, the 1917 is about equal in rarity to the 1915, 1916, and 1918. In Gem condition, the 1917 is about equal in rarity to the 1914, and it is rarer than the 1915, 1916, and 1919, but not as rare as the 1918. As a group, the 1914 to 1919 Philadelphia Mint issues are not quite as rare in Gem condition as the 1920 to 1924 issues, then beginning in 1925 many more examples were saved (thank you, Wayte Raymond!) The 1917, like most Philadelphia Buffalo nickels, is usually very well struck. Luster can be somewhat satiny to somewhat frosty.
