Ron Guth: The Proof 1889 Quarter Dollar benefits from the low mintage of its circulation strike counterparts. Only 12,000 Mint State 1889 Quarters were made, placing considerable pressure on the Proofs by collectors who need an example of this date for their collections. Proof examples of this date are fairly plentiful in PR63 to PR65, but anything nicer is decidedly rare. Cameo examples make up approximately one-fifth of the total population, whereas Deep Cameo examples account for less than three percent.
The finest 1889 Proof Quarter is a single PCGS PR68 (non-Cameo).
