Nicola White said she found the coin from the 1600s on the grounds of Sausmarez Manor last week.

The coin, worth 1/8th of a Livre Tounois, a medieval French currency, dates back to between 1655 and 1658 during the reign of Louis XIV.

Ms White said the coin was considered “rarer than scarce” and she also found a modern gold ring and current currency during her search, BBC News reports.

The coin has since been given to the land owner.
