The 1792 Disme in copper with a reeded edge. The illustrated piece is the ex Ellsworth, Garrett, Southern collection, Simpson collection and is believed to be the finest collectible. The example in the Smithsonian is probably the finest known and the former Dr. Judd and 73 ANA examples also grade uncirculated.
There are about 20 known of J10/P11 including examples impounded in the Smithsonian, Durham Western Heritage Museum, Independence Hall and Eric Newman collections. Most appear to have the normal vertical reeded edges. Virgil Brand owned at least 5 of these.
There are 3 examples of J9/P10 in silver with normal vertical reeded edges as follows. These pedigrees have been updated based on information in Stacks 10/2000 sale.
1) Dewitt Smith, Brand (journal #46511), Judd, Kosoff and Kaplan 1960s FPLs, Partrick.
2) Mickley, Cohen, Ulex (Lyman Low 1902 sale lot 431)?, Jewett, Col Green, Norweb. This is a thick planchet specimen with the date removed. Stacks lists this as being ex-Brand, but, if Brand did buy it, it was after the Jewett sale. Both this and the next appear in the F.C.C. Boyd's appraisal of the Col Green inventory sold in Kolbe-Fannings January 2012 sale.
3) Seavey (1873 Descriptive Catalog #839), Parmelee, Steigerwalt (offered in his fixed price lists), Granberg-1914 ANS exhibit, Newcomer, Col Green, Starr, Stacks 10/00.
It is possible that the Granberg and Brand pedigrees are reversed but based on current information, this is the most likely scenario.
There are also 3 examples of J11/P12 known in copper with a plain edge as follows:
1) Mint collection, Maris, Garrett, Bowers and Ruddy's Garrett IV sale - gem Unc
2) Stacks 4/44 lot 569 ?, Lohr, Roper as AU, Stacks 10/05, southern collection, Simpson collection - NGC61BN, overgraded
3) Authenticated at the 2004 ANA, Goldberg 2/05 gem but defaced - illustrated below courtesy of Ira & Larry Goldberg's Coins & Collectibles.
