Significant examples:
PCGS Proof-65.  Ex - B. Max Mehl "Jerome Kern", 1950 - Louis Eliasberg, Sr. - Bowers & Merena Galleries "The Rarities Sale", July 31, 2002, Lot 210, illustrated, sold for $87,400.00

"Proof-63".  Ex - R.C.W. Brock - J.P. Morgan - American Numismatic Society.

Proof.  National Numismatic Collection at the Smithsonian Institution.

Proof.  Discovered in the 1940s by Oscar Schilke in a complete silver and copper 1842 Proof Set - purchased (the complete Proof Set) by Arthur M. and Paul Kagin - purchased (just the Quarter Dollar) circa 1960 by Q. David Bowers - Hazen B. Hinman - Paramount "Century Collection", 1965.  This pedigree of this example may continue with the next example.

Proof.  Stack's "R.L. Miles, Jr.", 1969 - Stack's "S.G. Steckler", 1974 - Stack's "Ellis H. Robison", 1982

Stack's "James A. Stack", March 13-15, 1975 - Julian Leidman - Paramount International Coin Corporation.

According to Q. David Bowers, Breen's listing of known examples contains a couple of errors.  First, the Robison coins is not ex - Smith - Kern.  Second, John Jay Pittman (the "New York State specialist") never owned one (the coin in his 1842 Proof Set was a Prooflike Uncirculated 1842 Large Date Quarter Dollar).
