Best source for Crystal Skull Nazca tomb gold coins?

[Liberance]

I'm not too familiar with this prop. The coins scattered over Orellana's tomb when Indy and Mutt first discover the skull, like the one that gets attached magnetically to the skull.

Any Indy experts know what coins were used and where to find them? They look like the same basic gold doubloon from One Eyed Willy's treasure room in The Goonies, but I can't quite tell.
