The Helmingham-Suffolk hoard has finally come up for auction (see original post below). George Ridgway discovered a suspected coin hoard in September 2019. It consisted of 748 coins dating from as early as 206 BCE through to AD 46-47 and was found at Helmingham Hall, Suffolk (see post below). The British Museum, as well as the Colchester and Ipswich Museums, retained 68 of the coins for their own collections. The remaining coins were left to Ridgway and the landowner for either their personal collection or public auction for profit. Around 680 coins of the collection were sold for over £130,000, exceeding the estimated £75,000. The proceeds will be divided between the landowner and Mr. Ridgway. “The location of the hoard, together with the date range, suggests the coins may have been buried by a long serving Legionary soldier from the XX Legion, who were stationed at nearby Colchester.” “The highest price of the sale was for a Denarius of Gaius Caesar, better known as Caligula, dating from AD 37-38 and decorated with a portrait of Agrippina, which sold for £7,000 against an estimate of £2,000-£2,600. A Denarius of Claudius, dating from AD 41-42, sold at the hammer for £5,000, despite an estimate of £1,500-£1,800.” https://www.bbc.com/news/articles/cjd5lm98j45o https://www.cointalk.com/threads/help-numidian-coin-found-in-suffolk-hoard.396627/#post-8348364
This is how a found hoard should be treated. A few coins kept by the three museums and the rest winding up in collectors hands.
