Assuming the coin is circulated, the 1904 Liberty Head double eagle is a very common date. For an accurate assessment of value the coin needs to be seen and graded. In general retail values for circulated coins are $1,560.00-$1,670.00 depending on the actual grade of the coin. Values are a market average and only for coins in collectible condition, coins that are bent, corroded, scratched, used as jewelery or have been cleaned have far less value if any to a collector or dealer.

No US dollar coins dated 1818
Face value unless it is crisp and unfolded.
Sorry no US Lady Liberty dollars dated 1820
There are NO US Liberty Head dollars dated 1846 but there are Seated Liberty dollars dated 1846. Consult a qualified coin dealer
The walking liberty design was used only for half dollars dated from 1916 to 1947. If it's a dollar coin dated 1902 it's a Morgan dollar. Look at the coin again and post new question.
Spot price today is $17.64 so about $15.00.
The U.S. did not print any bills dated 1956
None of the coins listed in this question contain any silver or gold. All are just face value.
Value depends on if it's a Walking Liberty half dollar or a Monroe Doctrine half dollar, both are dated 1923 and both have "S" mintmarks.
Please post a new question after you look at the coin again. A U.S. silver dollar dated 1850 would be of the Seated Liberty series not a Bust type or Liberty head.
Please look at the coin again. No U.S. one dollar coins are dated 1906. Post new question.
