Sometimes, actually fairly often, you can findall sorts of oddities within Byzantine coins. The culture is rife withoverstrikes, double-strikes, gross mis-strikes and other errors. Forexample, the above coin may be an example where two flans were stuck together,since there is no obverse strike at all. It is an AE Decanummium fromCarthage, struck in the year 14 for Justinian I. It measures 16mm and weighs 4.31g. and would normally be SB 269.
Because Byzantine coins were struck after 476 and because they were mostly minted in the Eastern Mediterranean, they are rarely found in Britain. On the database you will find several gold solidi (solidus). These coins are not that unexpected as finds in Britain because gold often travels long distances because it retains its value across different societies. However, there are an increasing number of copper Byzantine coins being found. There is an early group of coins, dating between around 498 and 650 which are generally found in coastal areas.
This does suggest that they reflect continuing maritime links between Britain and the Mediterranean, especially on the west and south coasts.
