The result is a substance that's chemically "identical" to some other element ~ but maybe with some minor differences here and there AND, best of all, with a different atomic weight than you'd otherwise have guessed.

Then it's not real silver.

Of course it's not "real" but it'll pass the chemical tests, and it's chemistry that makes the world go round.

I'm sure they can come up with something that has the same range of atomic weights as naturally occuring silver ~ if there really is such a thing.
