Help required with identifying this coin please

[XGenX 10]

Can anyone pleas tell me anything about this coin. It has been set in a 14 caret gold setting to be worn as a pendant.

Looks very old and maybe Egyptian or Byzantine?

Many thanks Gen

Probably a Spanish 8 Real Silver Coin, possibly from a shipwreck.

Yes you are correct - when I google it - there are many examples of it that look like it. Thanks for your response
