Trial plate

A Trial plate was a piece of metal used as a standard in the assaying of coins to determine a coin's accuracy and fineness.[1] Plates made from various metals including copper, silver and gold were used in events such as the Trial of the Pyx as benchmarks of quality.[2] A contender for the earliest known trial plate dates from 1279 and is held by the Royal Mint Museum in the United Kingdom.[3]
