I've found most of the times if it's the real deal it will have a stamp on it somewhere. But not always. The stamps can be very tiny!! The sure fire way to tell is get yourself a gold & silver testing kit. They sell just gold or just silver tests. And they also sell kits for testing both. But the cheapest way I've had it done is for free! I just take it to a jeweler or one of those We Buy Gold ! stores and they'll test the items for no cost.
Good luck!
Hope it's the real deal !! thumbsup01
If you can get some nitric acid you can test it with that. Nitric acid on silver turns white, on other metal it turns green. That's probably what's in those silver test kits. It works great to test suspected silver ware.
