David Akers knew of no Uncirculated examples of this date, but in the decades after his work, nearly a dozen Mint State specimens have entered the market. Most are baggy, low-end Uncs., but they are Mint State nonetheless. The best example is a PCGS MS63 that traded hands a few times in 2007-2009, but which appears to have found a good home. This particular example is also somewhat baggy, but it has strong luster and great, original "crust."

The 1873-CC is very similar in overall rarity to the 1872-CC. It is generally available only in well circulated condition, i.e. VF or EF. Reportedly a few uncs do exist but I do not known the present location of one.
