 Indeed, there is no telling exactly when any late Roman coin was lost, and in some cases they may have been in use well into the post-Roman period.As for new imports, the number known for this period has increased considerably in recent years thanks to the spread of metal-detecting.Hoards from this period are rare, but two have been found in recent years at Oxborough (2001) and Patching (1997), both dating to the later 5th century and the latter including no fewer than fifty gold and silver coins dating from the period up to c. 470.
