Ici http://www.beastcoins.com/Byzantine/JustinII/JustinII.htm pour un demi follis variante de SB 365, l'auteur écrit "Note: Variant for obverse attribute - Justin holding globus cruciger expected. This obverse is the type used on solidi, so I am listing it as a variant of 365, although this may be significant enough to warrant a separate listing number" et plus bas, on trouve un avers très proche de celui de la tienne, mais avec légende, et c'est un decanummium avec ce commentaire : "Justin II, Æ Decanummium, Year 1 (565/566), Theoupolis (Antioch) D N IV_STI-P P AVG Helmeted and cuirassed bust facing, Victory on globe crowning emperor in right hand, cross in right field Large I surmounted by cross, A/N/N/O to left, */I/* to right, THEUP' in exergue 22mm x 24mm, 4.42g SB 382 Note: Sear describes the obverse as "legend blundered and often unintelligible". Luckily, this coin has a very clear legend, so the type sometimes was engraved carefully enough by the celator." http://www.beastcoins.com/Byzantine/JustinII/Z2804.jpg
Puisque les graveurs mélangeaient les avers et revers, je me demande si le tien n'est pas un demi follis avec l'avers du decanummium SB 382.
