Anyone done any #MetalDetecting around #Warrnambool?
I think this #coin is #Portuguese maybe? No idea of the date.
A tiny silver thing that is about sixpence sized.
PeterThis coin is a silver 80 Réis from Portugal, featuring a cross with quatrefoils in the angles on the reverse.
The text reads "IN HOC SIGNO VINCES", which translates to "In this sign you shall conquer."
Coins with this design were minted during the reigns of various Portuguese monarchs, including Pedro II, João V, and Maria I, ranging from the late 17th to the late 18th century.
These coins were typically struck in silver, with a fineness of approximately 0.917.
@John oh, and your example was minted during the reign of Pedro II (PETRVS II), 1683-1706.
