A year or so after a mysterious mint in Asia Minor (dubbed the 'o' mint) struck a rare series of denarii an even rarer issue of bronze appeared in the same region. The two issues are linked by similar circulation patterns and somewhat similar styles. The bronzes are imprecisely dated to the 77-78 time period but were likely struck for only a brief period, judging by their extreme rarity. Three denominations were produced in orichalcum apparently using a provincial weight system. The unique legends are in Latin and the reverse types copy those struck in Rome, but many have obvious 'Eastern' themes. The crossed cornucopiae seen on this coin likely echos a similar 'Eastern' themed reverse struck in Rome and on other eastern civic issues.

Admittedly, the link to the infamous 'o' mint is tenuous at best, but it is the most sound theory proposed so far (M. Grant, 'Asses of Orichalcum', Centennial Publication of the American Numismatic Study, pp. 285-302).

Dark black and green patina and nicely centred.
