Two Jersey metal dectorists discovered the largest ever Celtic coin hoard in a field in Grouville in 2012.
Richard Miles and Reg Mead made headlines around the world when they discovered the treasure.
Archaeologists are painstakingly working to take the collection apart.
What is believed to be a leather purse has been uncovered in the Grouville Hoard, a trove of Celtic coins found in Jersey.
Experts say it is about 80x40x40mm and is attached to two copper alloy rings, which may be a fitting for wearing it on a belt.
They reckon there's about 20 coins inside the purse and are keen to extract them.
So far it’s the first actual container of coins found inside the hoard.
Members of the public are being invited to watch the live extraction of gold jewellery from a huge Celtic coin hoard found in Jersey.
Around 12,000 coins have separated from the potential 70,000 total, but what's among those coins that is interesting archaeologists most.
