They are often associated with everyday items, but one charity shop has sold a rare stamp for the princely sum of £220.
The £1 stamp, marking the 1929 Postal Union Congress, was one of a several in an envelope delivered to the Break store in Sheringham.
Shop manger Tim Harvey, a keen philatelist, immediately spotted the value of the stamp, which was sold at auction.
He said: 'It is quite a rare stamp and not many people would have used it as a £1 was quite a lot of money in 1929. It would have been worth even more if there were not folds on the back.'
A stamp day will be held Saturday at the Break shop on Station Road from 10am to 4pm.
