"At the recent Gettysburg show, I had the good fortune to come across a nice electrotype of the very rare 1786 Neo-Eboracenesis copper. While I've seen genuine pieces, I have never seen an electro, so I quickly bought it.

"Arriving home, I checked the fixed price lists of Charles Enders, Jr. and Scott Stamp and Coin. Both offered electrotypes of the "more common" 1787 Nova Eborac, but neither listed the Neo-Eboracensis. Over the next few days, I searched various auction websites and could not find one sold in the last 20 years.

"I then searched the 19th and early 20th century auction catalogs on the Newman Numismatic Portal and found only two listings. The first was in a July 1865 McGilvray sale, where it was noted as a "copy," so probably an electro. The other was in a March 1885 Haseltine sale, cataloged as an electro.

"Do E-Sylum readers know of any other electrotypes of this piece?"
