The Eparch Collection of Roman, Byzantine and Islamic Weights
LATIN COMMERCIAL WEIGHTS

Western Mediterranean / North African Area. Circa 7th-9th centuries, possibly Carolingian. Weight of one ounce (or gaming piece?), inlaid with silver (Bronze, inlaid with silver, 21x6mm, 24.24 g), a thick, circular commercial-weight with centering holes on both sides, a slightly convex top and a plain edge (as MAH A1), ounce of 24.24 g. +IOHSELIADI, deeply engraved and inlaid with silver; at the center, centering hole within a circular incuse area. Rev. Plain, but with barely visible remains of an circular incuse border. No parallel found. A most curious item. The technique is definitely late Roman-early Byzantine in flavor: and the circular legend begun by a cross is very Western. Dark patina with some encrustations as found, otherwise, very fine.

From the Eparch Collection.
The only weight known to the cataloguer that is similar to the present example is the one that appears in the previous lot, and those cited in the notes to that piece.
