Estimated grade. Ex. Memorable Sale (1948) Sold by David Akers Numsimatics, May '98.
David Akers (1975/88): Proofs are extremely rare but exist in greater number than other proofs prior to 1859, except those of 1843 which are comparably rare.
Only four Proof 1845 $10's have survived out of an unknown, obviously tiny mintage. The finest is the PR66DCAM in the National Numismatic Collection at the Smithsonian Institution. That coin was obtained directly from the U.S. Mint in the year of issue and has been carefully preserved ever since. The next best is the former John Jay Pittman coin, once part of a complete 1845 Proof set housed in a contemporary presentation case (that set has since been broken up and the 1845 Eagle reappeared in a Bonham's sale in 2013, where it brought $444,600). The third is the ex Garrett coin that was last seen at auction in 1999. The fourth, also once a part of a complete 1845 Proof set, passed through the hands of Ed Trompeter, a connoisseur of Proof U.S. gold coins -- it's present whereabouts are unknown.
