Douglas Winter: With very few exceptions, all 1873-CC issues (in silver and gold) are quite rare and the 1873-CC eagle is no exception. I rank the 1873-CC as the third rarest Carson City eagle in overall rarity and it may actually be the single rarest in high grades. I doubt if more than a half dozen properly graded AU pieces exist and there are currently no 1873-CC eagles known that are even close to being Uncirculated. The single finest I am aware of is in an East Coast collection (it was acquired from me via private treaty in 2008) and it grades AU55 at PCGS. As with the 1870-CC, this date is rare because of two factors. A limited number were struck (just 4,543 in this case) and many saw active use in circulation (and were later melted). Survivors are apt to be heavily worn and even accurately graded EF's are quite scarce. This tends to be a decently produced issue in terms of strike but nearly all known examples have little or no luster, abraded surfaces and poor overall eye appeal.
David Akers (1975/88): In overall rarity, the 1873-CC is comparable to the 1872-CC, 1875-CC and 1876-CC, and somewhat more rare than the 1871-CC, 1874-CC and 1877-CC. The typical 1873-CC is softly struck on the hair curls around Liberty's face. The 1873-CC is unknown in uncirculated condition.
