The current face value of all presidential dollar coins is $1. Remember, they're brass, not gold. Presidential dollar coins minted at Philadelphia and Denver are worth a dollar even if they are uncirculated. Proof-quality presidential dollar coins minted at San Fransisco are worth $3.
Post a new question with the date. All Silver Dollars since 1878 have this Latin phrase that is a national motto. Also it appears on all U.S. coins from 1938 to 2011.
Check that coin again. The Hayes dollar would have the dates 1877-1881 on it, as those are the years he was President. The coin itself was minted in 2011, and is worth one dollar. Coins dated 1776-1976 were bicentennial Washington quarters, Kennedy half dollars, and Eisenhower dollars.
The rate fluctuates, at present (April 2011) one Euro is worth about 1.30 dollars

August 2011... They are worth 5 to 12 dollars in circulated condition. In uncirculated condition they are worth 45 dollars or more. This is not a rare date.
It depends on what you're calling a "Liberty dollar". All US silver dollars minted up till 1935 had a picture of Miss Liberty on the front. These are worth at least 75% of the current price of an ounce of silver, around $20 as of early 2011, and many of them are worth a lot more. The "dollar" bullion coins minted since 1986 aren't for spending and aren't really silver dollars but are worth a bit more than the price of an ounce of silver. Circulating $1 coins minted since 1971 don't have any silver and are only worth $1. If you have a specific coin you want to evaluate, please post a new question in the form "What is the value of a (date) US silver dollar?", where (date) is of course your coin's date.
