King Edward III leopard coin = £140k

Edward III (1327-1377)

An exceptionally rare gold coin unearthed by a metal detectorist in England made £140k at auction. The coin was minted in the Tower of London from 23-karat gold. It is one of just a handful of surviving leopard coins from a failed currency experiment by King Edward III. The coin was discovered in 2019 in North Norfolk, and only four others are known: two in the British Museum, one at the Ashmolean Museum in Oxford and one is in a private collection.
