A coin with a doubled mint mark is called a RPM, short for re-punched mint mark. These exist in all denominations and over many different years. The Lincoln cent and Jefferson nickel are the coins with the most well known RPM's. There are literally thousands of different varieties of RPM's, so it's hard to narrow down which is the one you are referring to.
If your coin does not have a mint mark then it means it was minted at the Philadelphia mint. These coins are usually not as rare. However recently P mint marks were added to coins to indicate that they were made at the Philadelphia mint.
That is very dependent on the mint mark if it has no mark or a "D" mint mark it is fairly common with values as little as $1 to over $60 depending on the condition of the coin (grade). If it has a "S" mint mark it is a rare coin and can be valued anywhere from $100 to over $1000 depending on the grade of the coin.The only way to get an accurate valuation is to take it to a coin dealer and get an opinion that way, its very hard to give a value without seeing the coin.
No mint mark simply means it was minted in Philadelphia. It's not a rare coin, and is currently worth about 5 cents.
If it was minted in 2009 and later, the date and mint mark along with the phrase " E Pluribus Unum " are on the rim and not on the obverse or reverse of the coin.

The earliest the coin was produced by the US mint, the more rare it probably is. However, the mint state would also contribute to the coin's value.

In 1993, the US Mint produced a American Eagle Silver Bullion proof coin with a mint mark of "P." The 1993 coins that carry a mint mark of "S" and "W" were in a mint state of MS65. Mint State (MS) is a value used to grade the condition of the coin. This range runs from MS60 (not a good quality collector coin) to MS70 (a near perfect UN-CIRCULATED coin) sold directly by the U.S. Mint. The "S" and "W" mint marks indicate that the coin was minted at either San Francisco (S mint mark) or West-point (W mint mark). Even though these coins were specially minted and handled they may have a grade less than MS65 and, in rare cases grade higher than MS65

1911 is not a rare year for Barber dimes.

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.

If it does not have a mint mark above the date, it's worth about $1100. If there is an "S", it's worth about $4000. If there is a "D" it should be authenticated to make sure it's not a counterfeit, as this date/mint mark combination is considered to be extremely rare.
No circulated bicentennial dollars are rare. If it's a silver proof, it will weigh more than a regular Eisenhower dollar, and it will have the mint mark S.
