Yep, it's legal tender so you can spend it.
You should be able to find a Franklin Pierce dollar coin .
A half dollar coin weighs 11.34 grams and a dollar coin weighs 8.1 grams so if you use subtraction then the answer would be 3.33.
No.
The coin they use is called the Jamaican dollar!
The Royal Mint has never issued a 5 Dollar coin for British use, much less one with a "5 Dollar" symbol on it. The British use the Pound and issue a "5 Pound" coin, but not in 1988. The coin is possibly from one of the 50 plus Commonwealth countries and should have the country name on it somewhere, most likely Australia, Canada or New Zealand.
They now use a $1 coin irreverently called a loonie because it carries a picture of a swimming loon.
No such coin (that is intended for circulation) exists. The last silver dollar coin was minted in 1935. The only other coin since then to use the silver dollar size was the Eisenhower dollar first minted in 1971.
An 1857 Indian Head gold one dollar coin should weigh 1.672 grams.
Ireland does not use the dollar and never has, so there is no such thing as an Irish 1 dollar coin. Ireland was using the pound in 1952, but there was no 1 pound coin. So whatever coin you have, cannot be either an Irish one dollar coin nor an Irish one pound coin from 1952.
yeah.
Go to the bank and get a 1 dollar coin. Any large bank should have plenty of Sacajawea and Presidential $1 coins.
An 1891 dollar coin is a Morgan dollar, and therefore should weigh 26.73 grams. (This is the official weight when issued from the mint. If the coin was substantially circulated, it may weigh less due to wear.)
