CNG 103, Lot: 100. Estimate $4000. Sold for $3000. This amount does not include the buyer’s fee.

THRACE, Byzantion. Circa 175-150 BC. AV Stater (20.5mm, 8.48 g, 11h). In the name and types of Lysimachos. Diademed head of the deified Alexander right, with horn of Ammon / BAΣIΛEΩΣ ΛYΣIMAXOY, Athena Nikephoros seated left, left arm resting on shield, transverse spear in background; monogram to inner left, BY below throne, ornate trident in exergue. Marinescu Issue – (O122/R– [unlisted monogram]). Near EF, some die wear on obverse, a few scuffs on reverse. Extremely rare.

From the M. A. Armstrong Collection.

The left field monogram is not recorded by Marinescu, but the obverse die is known for his Issue 109, which allows a contemporary dating for this coin. It appears that the monogram here was engraved over a monogram that was erased in the die, and the remnants visible are consistent with the monogram of Marinescu Issue 109.
