Hello and welcome. I hope we can help. 
The "sovereign" was (and still is) a British gold coin, face value 1 pound, and was never struck in silver. I suspect your coin is a British "crown", face value 5 shillings or 1/4 or a pound. They're big and heavy (though less than a troy ounce) and the ones from the 1890's have the same design as the gold sovereign on them: St George slaying the dragon.

Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
