CNG 91, Lot: 967. Estimate $500. Sold for $1000. This amount does not include the buyer’s fee.

Honorius. AD 393-423. AV Solidus (19mm, 4.36 g, 6h). Constantinople mint, 6th officina. Struck AD 395-402. Pearl-diademed, helmeted, and cuirassed bust facing slightly right, holding spear and shield / Constantinopolis seated right, holding scepter and Victory on globe, foot on prow; dot to right of exergue line; S (retrograde)//CONOB. RIC X 8; Depeyrot 55/2. VF, a few small contact marks, traces of deposits. Extremely rare with retrograde officina mark.

In the note to RIC X 8, Kent cites an example for the retrograde officina mark: G. Hirsch 137, lot 361. Unfortunately, this is in error, as the Hirsch coin has the S officina mark in its normal form, not retrograde.
