In 2011 a small coin hoard was found at Rock in Worcestershire by metal detectorists. It was reported to the Portable Antiquities Scheme and has recently been acquired for the county collection by Museums Worcestershire.
The Rock silver pennies are of the short cross type and date to the reigns of King Henry II, King John and King Henry III (1180 to 1229). They were, perhaps, once stored inside a purse which lay lost in the Worcestershire countryside for nearly 800 years.
The short cross penny was introduced in 1180 following years of abuse of the currency and inferior workmanship, a situation exacerbated by the civil wars of the twelfth century. The coin gets its name from a cross with short arms pictured on the reverse.
The short cross on the reverse of these coins is where the problem lay. The arms of the cross did not extend to the edge of the coin and clipping the edges of coins to gain the precious metal became common. The long cross penny, with arms that extended to the edge of the coin preventing clipping, was introduced to eliminate the problem.
