A father and son found eight late Roman coins which archaeologists believe came from a hoard near Mildenhall, an inquest heard.
The silver coins, known as siliquae, were discovered by Steve Foster and his son Nick in December last year.
On Wednesday an inquest at Bury St Edmunds was told by Faye Munter from Suffolk County Council’s archaeological service that coins from the hoard have been coming to light since October 2001.
The rest of the hoard is in Mildenhall Museum, which hopes to acquire the last find. Suffolk Coroner Dr Peter Dean declared the coins as treasure.
Another inquest heard that part of a silver buckle plate found at Lakenheath by Chris Clarke last April was an example of Medieval recycling. Dating back to the late 5th or early 6th century AD, it appeared to have been reused at a later date.
The plate was also declared as treasure.
