AN engraved disc commemorating a dastardly deed by a highway robber goes under the hammer next week.

On March 14, 1768, John Curtis was hung for the robbery and murder of Wolf Myers, on the road near Salisbury, Wiltshire.

An engraved disc produced by a local craftsman hoping to profit from the execution will be sold at Tennants Auctioneers, in Leyburn, North Yorkshire, next Wednesday.

Jeff Gardiner, a coins, medals and medallions specialist from Tennants, said: "The penny was discovered in a miscellaneous box of coins by a private collector from Darlington. This is a fantastic find."

The Salisbury Gibbet Memorial Penny is estimated to fetch between £60 and £80.
