Google Print brings Die Unächtheit der jüdischen Münzen mit Hebräischen und samaritanischen Buchstaben by Oluf Gerhard Tychsen. Published in 1779! Not in ANS library.
I had never heard of the book or the author. He has a Wikipedia entry.
I know almost nothing on numismatic books before the 19th century. I've been considering the purchase of Bassoli's Antiquarian Books on Coins and Medals to correct this deficiency. Has anyone actually seen/read Bassoli?
