In 1940 through 1946, half crowns weighed 14.138 grams and were 50% silver - they thus contained 0.2273 troy ounces of silver. In 1947, the half crown (and all other "silver" British Coins) were changed to cupro-nickel, and thus contain no silver at all.
Really depends on the date and condition. British half-crowns before 1947 are silver and worth substantially more than the ones dated 1947 and later. The ones before 1920 are sterling silver, worth more than the 50% silver ones of 1920-1946. But post a date if you want an accurate evaluation.
It depends on the year. Up through 1919, it was sterling silver (92.5% silver), then in 1920 it was reduced to 50/50 silver and copper, and changed again in 1947 to a blend of copper and nickel, with all silver removed.

The half-crown and crown are obsolete British coins. Under the old pre-decimal system, one crown was worth five shillings, and the half-crown was worth half that. At twenty shillings to the pound, the crown was 1/4 and the half was 1/8 of a pound. Or, the crown was 60 pence and the half was 30 pence.

Post-reform coinage like the half crown you are mentioning are pretty common and so its unlikely to be faked. If you are concerned about it being fake, weigh it. It should weigh about 14.1 grams.
Please check the coin's date and denomination US silver dollar production was suspended between 1905 and 1920 inclusive, so there are no 1917 dollar coins. If your coin says HALF DOLLAR on the back, it's a half dollar, not a silver dollar.
