Hi Geoff,
Sorry should have included that in my original question, not sure I can edit it now.
The coins are all either current 50p pieces or £2 coins, including a Beatrix Potter 50p going for £10-£20 on Ebay for example. So in theory they could be paid into the Client account as you would any other cash found at a property.
Our Firm is the sole Executor of the estate. The Will has various specific gifts of possessions, none of which include the coin collection.
Thanks
