Sorry I've read my answer again, I can see that it is not clear. When I
say that there is 0% chance that a Golden Eagle coin doesn't actually
contain the gold (aka written "SUCKER" on it), I talk about a genuine
Golden Eagle produced by the official mint factory, I'd like to see if
they took the risk of producing only one coin in their entire career
that doesn't contain the gold, I bet there is not, that's why I say 0%
chance. Of course fake Golden Eagle doesn't contain the gold, but the
technology detects it right away, to produce an official Golden Eagle
coin with its UUID registered on the blockchain you need to have access
to their official private key.

Please tell me if it's still unclear.

Thanks,

Camille.
