Was watching this earlier. A Chap came on with an 18ct gold and diamond bracelet. He had found it in amongst a box of odds and sods he bought at a boot sale. Hadn't noticed it until he was looking through the box some time later. The bracelet was only made in 2015 so new. I can only think that it was put in by mistake or had fallen into the box from someone who was at the boot sale. I'd have tried to reunite it with it's owner. It's not as if the person would have known it was in there it was worth £3K new and he had given £10 for the box!
What would you have done?
