What's this coin called? i found it on a shipwreck website.
It's a Spanish piece of eight.
It looks to me more like an Escudo than a piece of eight.
This web page identifies it as 1 escudo piece, worth possibly $2,500 nowadays.
At the time of minting, it seems, an Escudo was worth 16 Reales. A piece of eight was worth 8 Reales.
