It deprnds on the date and condition of the coin
It depends on how good the coin looks... if its all old looking and gross, its not worth as much as it would be if it was cleaner. Also it depends on the date of the coin... older - more $ its worth. the newer - not-so-much $. sorry ;)
If it is an old coin it could be worth something depending on the date and the condition.
How much is this coin worth 186 year old
it depends on how old it is.
20,000,000 because its very old.
It depends on the condition of the coin. There is a rating system that is used to classify the worth of old coins and it is based on the amount of wear and damage to the coin. Take it to a coin shop to get an idea.
It really depends on the date of the coin, post new question with a date.
5 Israeli shekels = 1.331205 U.S. dollars
It is worth 25 cents, or one quarter of one dollar. 1966 is not old enough for the coin to have gotten valuable.
Depends on the coin
No 1912 U.S. silver dollars were made, look at the coin again and post new question
