Yes, the 1937-D Nickel is a very common coin in most grades, but let's talk about condition rarity. Thousands of examples of this date have been certified in MS64, MS65, and MS66 condition, but in MS67, the population drops off dramatically. MS68 is where this date shines (literally). In March of 2015, one of the two PCGS MS68 examples sold for an amazing $35,250, setting a new, remarkably high record for the date, and pretty much for any late-date Buffalo Nickel.
The 1937-D is a common Buffalo nickel in all grades. Only the 1937 and 1938-D are easier to find in mint state and Gem condition. Strike is usually very sharp and luster is typically quite frosty.
