Three or four knights involved in his murder are depicted to the right while Edward Grimm is shown on the left with his arm is raised in an attempt to protect Becket from the sword blow of William de Tracy and perhaps holding a cross. This is an item of great local importance and there was a chantry dedicated to St Thomas Becket in the chapel of Holy Trinity in Richmond in the early 13th Century.


Discovered by a metal detectorist near Richmond and declared Treasure in 2007.
