Overview

Historical significance

Under Justinian I, Byzantine coinage underwent a major reform in 538 AD. This coin reflects the peak of the Empire's power, including the reconquest of Italy and North Africa. The introduction of the frontal portrait replaced the traditional Roman profile.

Obverse (front)

Helmeted and cuirassed bust of Justinian I facing forward, holding globus cruciger and shield. Legend: D N IVSTINIANVS P P AVG.

Reverse (back)

Large letter 'M' (Greek for 40), cross above, 'ANNO' on left, 'XII' (Year 12) on right. 'E' (5th officina/workshop) below M. 'CON' in exergue.

Estimated value

$1 - $5 (As a modern replica/souvenir). Genuine examples range from $40 - $250 depending on condition.

What drives this coin's value

The most significant factor here is the 'H' in a circle on the obverse, identifying it as a modern reproduction rather than an ancient artifact.

Grade assessment

Extremely Fine (if genuine), but lacks the sharp striking characteristics of an authentic 6th-century coin.

Mintage & rarity

Common (as a type), but this physical item is a modern reproduction.

Authenticity & counterfeit red flags

Look for the small circled 'H' on the obverse right field; this is a hallmark of modern museum replicas. Real coins have sharper edges and show 'striking' characteristics rather than 'casting' characteristics (bubbles, soft edges).

Notable varieties & errors

Genuine varieties include different years (XII through XXXVIII) and different mints (Nicomedia, Antioch, Carthage).

Similar coins

Follis of Justin II or Maurice Tiberius, which also use the large 'M' design but feature different portraits and names.

Care & preservation

This specific piece is likely a modern souvenir; no special numismatic care is required. For genuine coins, avoid cleaning or scrubbing, as it destroys the natural patina.
