The 1883-CC $1 is one of the most common dates issued by the Carson City Mint. Large quantities of full bags of $1,000 face value appeared in the 1960s in U.S. Treasury vaults, accounting for most of the known population. These were distribued in the late 1970s and early 1980s by the General Services Administration, which sold individual coins to dealers and collectors. Today, they are extremely common and can be found with ease in all Mint State grades up to MS67+. The most frequently-seen grade is MS64, where PCGS alone has certified over 15,000 examples (as of July 2015). In general, coins of this date show strong strikes and deep, frosty luster.
Prooflike and Deep Mirror Prooflikes are scarce and represent about one-seventh of the total population. Both appear to be of similar rarity. Gems are readily available in these formats, too, but they are usually more expensive because of their distinctive appearance.
