No when you buy generics like this for very low price over spot they usually don't come with a certificate. That's why they're not marked up as much as pieces that do come with the certificate.

I like to keep a variety--some like this and some that have the certificate. This was just a trial run buying with crypto so I was just looking for something inexpensive. I suppose if I really wanted to verify they're not fakes I could measure their weight vs volume to verify they're silver. But that doesn't verify that it's 0.999.
