A coin linked to a promise made in 1971 has been discovered in Bicester, raising the prospect of an unusually delayed reward: a pint of beer. BBC Business identified the finder as Ellie Mead.

The key evidence is a card found with the item. Its brief message read: "one pint best beer if penny returned". The wording indicates that returning the penny was the condition attached to the beer offer.

The report’s headline describes the coin as having been hidden in 1971 and says the find earns its discoverer a free pint. However, the supplied evidence does not establish whether Mead has returned the penny, contacted the person or organisation behind the card, or received the drink.

Important details about the original arrangement are also not yet known. The available report does not identify who wrote or issued the card, where the penny was concealed, why it was hidden, or the establishment at which the promised pint was meant to be claimed.

It is therefore unclear whether the offer remains redeemable after more than five decades. What can be confirmed is that Mead’s Bicester discovery has recovered a written promise exchanging the return of a penny for one pint of what the card called "best beer".
