About this source
What it is
This is a fragment of a silver penny from the London mint, dating from the reign of King John. The record says roughly one third of the coin remains, and its central part with the bust and cross is missing. Two photographs show the curved, worn fragment with a short cross design and a scale bar. The coin is a short cross type, class 6a2, and its moneyer was Ilger.
Why it matters
Magna Carta was agreed in 1215 during John's reign, and coins from the London mint were the everyday money of his kingdom. A broken coin shows that money was valued and reused, sometimes cut or damaged, and that it moved through many hands. Such objects help students connect the king's government to the lives of people who handled his money.
