Mint marks were first used by the Greeks as early as the 1600s to identify the mint and or inspector of a coin should a problem arise such as an incorrect weight or tampering. Today, the US still used mint marks to record where a coin was made. Common mint marks on US Coins are P for the Philadelphia Mint, S for the San Francisco Mint, W for the West Point Mint, and D for the Denver Mint. Other countries may also use the "d" mark to indicate their own mints. Most use the first initial of the city in which the mint is located, but that is not always true. For instance, a "D" on a German coin means it was minted in Munich.
There's never been an "oo" mint mark on a US coin. The only two-letter mint mark was "cc" for Carson City, 1870-1893.
Many 19-century coins used so-called serif lettering with extra descenders and trailers on each letter so a "cc" with serif lettering could appear to be "oo" unless you examine it very closely.
Mint mark positions on US coins vary depending on their date and denomination, but in general they were on the reverse side during the time that the New Orleans Mint was in operation. The most common position was above or below the wreath, or below the eagle, again depending on design.
The only exceptions for New Orleans' mint mark were half dollars minted in 1838 and 1839, and quarter eagles minted in 1839. These had the mint mark position on the obverse above the date. In 1840 the position was standardized to below the eagle on the reverse.

In most cases all coins with a specific date and design have the same mint mark position regardless of where they were struck, so the same criteria apply to all mint marks rather than just New Orleans.
Of course Philadelphia's "P" didn't appear until the mid-20th century, and there were some transitional periods when positions were changed in the middle of a year. Bottom line, it's important to check a reference guide when looking for mint marks.
The "O" is the mintmark of the New Orleans mint. What is it worth
The mint mark O was for New Orleans.
New Orleans.
The mint mark "O" represents the U.S. Mint located at New Orleans. In 1878 this mint did not produce any silver dollar coins. What you probably have is Carson City Morgan. The mint mark would be "CC" but I suppose that on a worn coin or one suffering some sort of damage it could appear to be "OO". Carson City Morgans are generally less numerous that those of other mints and carry a greater value. I would suggest you take your coin to a reputable dealer and have him determine exactly what you have since I can only speculate about it having not seen it myself.
The mint mark is below the date.

There is not always a mint mark on coins. If your coin does not have a mintmark it means that it was made at the Philadelphia mint in Pennsylvania.
A mint mark tells where the coin was minted, for example, a P mint mark (or in some cases no mint mark) signifies the coin was minted in Philadelphia, D is for Denver, S is for San Fransisco. I'm assuming someone told you that the mint mark was under the eagle for whatever coin you had, so you simply need to look under the eagle to find a mint mark. Keep in mind that some coins were produced in the Philadelphia mint and have no mint mark.
The mint mark of the Denver Mint (shown as a "D") and the San Francisco Mint (shown as "S) on the Eisenhower Dollar is located on the obverse (heads) side of the coin directly beneath the bust of Eisenhower. If there is no mint mark there, then the coin was struck at the Philadelphia Mint and in this mint did not place a mint mark on the coins struck there until 1979.
