You possibly have a very bad forgery or some sort of fantasy coin.
Queen Elizabeth II did not exist until the 2nd of June, 1953.
From the death of her father, King George VI, until her coronation in 1953, she was the Queen Regnant.
Prior to her fathers death, she was Princess Elizabeth.
Elizabeth ascended the throne in 1952 as Queen Regnant and was crowned in 1953 as Queen Elizabeth II.
There were no coins with her likeness issued prior to 1953.
Queen Elizabeth II was never the Queen of France.
The British Double-Florin (Four Shillings) was issued from 1887 to 1890 inclusive. The were made from sterling silver (0.925).
That's either a forgery or an error. Elizabeth II is the current Queen of England. No coin dated 1900 would have her name on it, as she hadn't even been born then, let alone become queen.
Queen Elizabeth I died in the 1600s and Elizabeth II was born in 1926. Also England uses pounds and not dollars. Please check what you have and post a new question. Describe the coin's size and designs. You do NOT have to include the strange Latin abbreviations because that appears on ALL British coins and doesn't help to ID anything.
No US quarters dated 1966 are silver. The only US quarters struck in silver are dated 1964 or before with the exception of silver proof sets (most proof sets are -not- silver and silver proof sets are marked as silver) but those are dated from 1992-present.
If it's dated 1964 or earlier, it contains 90% silver with 10% copper. If it's dated after 1964, it contains no silver.
If you have a U.S. silver dollar dated 1790, then you have a counterfeit. The mint did not start making silver dollars until 1794
1964 dated half dollars, quarters and dimes are 90% silver. 1965-1970 dated half dollars are 40% silver. Dimes and quarters dated 1965-present contain no silver Half dollars dated 1971-present contain no silver. No US coin dated 1971 (that was intended for circulation) contained any silver at all. No nickels except those made during WWII contain any silver at all.
No
Some British banks will offer this service, though possibly only with larger denominations, or they have a minimum exchange amount. Sixpence, shillings, florins, and half-crowns dated before 1947 are made of silver.
Yes, if they are dated 1935 or earlier they have 90% silver.
There were no British Shillings dated 1952 issued for general circulation. There are 2 Proof coins thought to exist, one is in the Royal Collection, the other possibly in the Royal Mint museum.
