Ron Guth: Proof 1858 Quarter Dollars are very rare. Estimated mintages range from a low of 80 Proofs to as many as 300. The PCGS Population Report suggests that the mintage of 80 Proofs is far too low and that the correct number is probably somewhere between 200 and 300 Proofs. Cameo Proofs represent approximately 20 percent of the total population; Deep Cameo Proofs are extremely rare.
The finest Proof 1858 Quarter Dollar is the Eliasberg example, now in an NGC PR67 holder. This particular coin has appeared on the market at least eight times since the 1997 Eliasberg sale and appears to have finally found a permanent home in 2016 (at a price less than 50% of its former high).
