Rusty Goe Southgate Coin
From its opening in 1870 to 1875, the Carson City Mint produced very few Dimes. At 35,480 coins, the 1872-CC had the largest mintage of the period, but that is such a tiny number compared to the more than 4.6 million 1875-CC Dimes made just three years later. Because of the distance between the Carson City Mint and the collectors back East, very few 1872-CC Dimes were saved. As a result, only a single Mint State example is known and the PCGS CoinFacts Condition Census drops all the way down to EF45.
The afore-mentioned Mint State example is the PCGS MS63 from the Battle Born and Eugene Gardner collections. Obviously the finest known representative of the date, it is on par with the unique 1873-CC No Arrows Dime. Every other CC-Mint Dime is known by at least two or more Mint State examples.
