Police are appealing for information after banknotes worth around £60,000 were mysteriously found floating down a river in Lincolnshire.
A dog walker spotted the cash near to Spalding town centre last month.
Officers who recovered the banknotes say a large amount was damaged but a good quantity appear to be in fair condition.
They are now trying to trace the owner.
If they cannot it will become the subject of a court forfeiture order.
