I'm assuming that you mean British and not US Coins.
British silver coins dated 1919 and before are sterling (92.5% silver)
While British silver coins dated 1920-1946 are 50% silver.
No British coin has been struck for circulation in silver dated 1947-present.
For the sterling coins:
Threepence - 0.0420 of a troy ounce
Sixpence - 0.0895
Shilling - .1682
Florin -.3364
Half-Crown - .4206
Crown - .8409
For the 50% silver coins
Threepence - .0227
Sixpence - .0455
Shilling - .0909
Florin - .1818
Half-Crown - .2273
In order to calculate the current values you need to multiply the silver price by the silver content. For example if silver was valued at $30 an oz and you had a 50% silver threepence, you would take 30 times .0227 which gives you a value of about 68 cents.
Pre-1965 silver coins are worth more for the silver than face value.

Go to www.kitco.com for spot silver prices. Spot silver prices only tell you the melt value of the coin. Many - but by no means all - pre-1965 (not pre-'63) silver coins are worth much more as collectibles than as bullion. You have to know the coins' dates, mint marks, and conditions to make any determination of their collector value. You can find price guides at many locations; one good one is www.Numismedia.com
A pound of silver coins is about $500.00
Pre-1965 US quarters are 90% silver with a value of about $2.50 just for the silver.
Pre-1965 silver coins are worth more for the silver than face value.
Due to the steep rise in the price of silver in 1919/20, the issue of standard 92.5% silver coins was discontinued and coins of 50% silver were minted. In 1947, silver was needed to repay the bullion lent by the USA during the war years, so silver coins were replaced with coins of the same weight and type made of cupro-nickel.
All New Zealand silver coins from 1933 to 1946 had a silver content of 50%. From 1947 onwards, all New Zealand "silver" coins were made from a copper-nickel alloy.
Last year for Canadian silver content coins was a partial production in 1968. A magnet will pick up newer quarters but not pre 1968 silver coins this includes dimes as well.

No way of supplying an answer. Hundreds of coins fit this description.
The coins have an Actual Silver Weight (ASW) of .36169oz of pure silver.
Pre-1964 US dimes, quarters, and half-dollars contain 90% silver by weight. A dime is approximately 2.5 grams of silver, a quarter is 6.25 grams, and a half-dollar is 12.5 grams, making it easy to calculate the silver content based on the face value of the coins. For example, a $1 face value in pre-1964 coins would contain approximately 0.715 ounces (20.17 grams) of silver.
