Hello Bianca -- You have a silver dollar designed by a man named George Morgan, so collectors call coins like yours Morgan Dollars. They are highly prized collectibles.
Your 1901O specimen is a 'common date' coin like most of the dates and mint marks in this series. 1921 is the most common of the common dates, as there were hundreds of millions of the 1921 coins made. Coins with better dates, not common dates, are listed below. They are more valuable.
To figure the value of a US Morgan silver dollar, start with its basic silver value. As the US dollar weakens, the price of silver goes up, and big silver coins start to get substantial valuable from silver content alone. Each Morgan silver dollar coin contains 0.773 troy ounces of silver. Using a web site like kitco.com, you can find the current price of silver per troy ounce, then multiply that price by 0.773 to calculate the base value of the coin, then add $3 or so to account for the fact that it's a US silver dollar. The value can't go lower than that. For instance, if the value of silver is $40 per troy ounce, the base silver value would be 0.773 x 40 + 3 = $34. If the value of silver is $20 per ounce, the base silver value is $18.50.
COMMON DATE MORGAN DOLLARS (coins with dates and mint marks not shown in the list below on this page):
worn: base silver value + $3 retail value
average circulated: base + $5
well preserved: base + $8
fully uncirculated: base + $15
MORGAN DOLLARS DATED 1921 (includes coins with mint marks):
circulated: base silver value + $3 retail value
fully uncirculated: base + $8
The values above are approximate retail prices, that is, prices paid by collectors or investors for Morgans they buy from coin dealers. If you want to sell your Morgan dollar to a coin dealer, he or she will pay substantially less than retail. The margin is used to keep the dealership afloat. For single coins, margins can be as high as 100%. For a large number of coins, margins can go way down.
Note: ff you have a 1921 peace silver dollar, and not a 1921 Morgan silver dollar (the picture on this page shows a Morgan dollar), you have a valuable coin. See our appraisal page for peace dollars at this link.
Never clean or polish your Morgan dollars. Cleaning, polishing, scraping, sanding, brushing, using steel wool, and all abrasive procedures ruin value.
NEVER CLEAN A COIN. CLEANING RUINS VALUE.
Most dates of Morgan dollars are very common, and the discussion above applies directly. There are, however, special dates and mint marks in the Morgan dollar series. Look for the mint mark (S, O, or CC) under the wreath on the back of the coin. Those with CC mint marks (CC = Carson City, Nevada mint), command very high prices. All CC Morgans are valuable. Here is a list of 'good date' Morgans which catalog above $100 in average circulated condition. The values at the right of each date is an approximate catalog value for coins in average circulated condition. To attain these values, a coin must be free of all problems such as sratches, spots, stains, cleanings, nicks, holes, dings, scuffs, and any other kind of damage.

Be sure you understand what 'catalog' means, as this is an inflated value. Check our Terminology page for an explanation.
Hope you have an 1895!
