Beat me to it. This is why I'd never buy a precious metal, especially gold. How can you ever be sure it's real?
Fairly simple XRF + thermal conductivity + resistivity tests will completely guarantee that a bar of gold is what it says on the face. For extra paranoia there's more complex ultrasonic testing.
If someone is desperate to sell it to you for bitcoin, it is probably real. Gold isn't doing too well at the moment.
If they don't care too much, it's probably fake.
