Please post new question with the country and denomination of the coin.
The dual dated Eisenhower dollars are face value only.
This is a good coin! Only 364.000 struck, worth: at least 300 dollars in good condition.
Sorry, no US dollar coins dated 1817
It depends on which denomination coin you have, but whichever one you mean, it's only worth face value.
It really depends on the condition of the coin, most are $3.00 to $5.00
If you have a "Silver Coin" dated 1816, it's not a U.S. coin. The only coin issued by the United States in 1816 was a Large Cent.
No US dollar coin is dated 1975, look at the coin again and post new question.
It was a common circulation coin until 2002 when Italy switched to the euro as its currency. At that time it was worth about a half dollar.
A denomination is needed. All U.S. coins dated 1898 have the word LIBERTY on them.
The Mint didn't make any 1975-dated $1 coins.
Yes it is. The value for the coin is about $3.00
