U.S. Coin Rolls: How Many Coins In A Roll By Denomination

Small Cents (Flying Eagle Cents, Indian Cents, Wheat Cents, Memorial Cents) = 50 coins with a face value of .50 cents
Nickels (5 Cents) (Liberty Nickels, Buffalo Nickels, Jefferson Nickels) = 40 coins with a face value of $2.00
Dimes (Seated Dimes, Barber Dimes, Mercury Dimes, Roosevelt Dimes, etc.)= 50 coins with a face value of $5.00
Quarters (Seated Quarters, Barber Quarters, Standing Liberty Quarters, Washington Quarters, etc.)= 40 coins with a face value of $10.00
Half Dollars (Seated Halves, Walking Liberty Halves, Franklin Halves, Kennedy Halves)= 20 coins with a face value of $10.00
Dollars (Morgan Dollars, Peace Dollars, Eisenhower Dollars, etc.)= 20 coins with a face value of $20.00
Small Dollars (Susan B. Anthony, Sacagawea, Presidential Dollars)= 25 coins with a face value of $25.00
Remember this, no matter what the coins are housed in, paper or plastic, a roll of coins will always contain the same amount of coins, if they are of the same denomination. There's exceptions to this rule since $1 nickel wrappers still exist and contain 20 coins instead of 40, but these are not readily available today.
Here is the best method of manually determining the amount of coins in a roll. Here's an example formula: Most should now know a roll of quarters have a face value of $10.00 and a one quarter is .25 cents, so we can divide $10.00 by .25 and this equals 40, and is the correct number of coins in a roll of quarters.  So, the next time you count your coins you won't be guessing how many go into each roll.

Nickels contain $2.00 and one nickel is .05 cents, so $2.00 divides by .05 cents equals 40 coins.

It doesn't matter if the roll is paper, bank wrapped or in plastic tubes, all contain the same amount of coins for each denomination.
Did you know you can find mint errors in rolls of coins? You should search your coins for mint errors before you roll them and check all rolls before you cash them in! I think I found a mint error.

Paper coin wrappers where the first material used for wrapping rolls of coins and often paper rolls would be torn or get wet, and fall apart with age. In turn, the coins would get wet, and this causes damage to the coins being subjected to such environmental elements. Plus, the chemicals used in making the paper wrappers will react with the coin causing it to tone or tarnish. Sometimes the toning is pleasing while other instances it's not.

Chemicals, plus water, are disastrous for most coin metals especially copper and steel. So better methods of storing coins was in order. This method of storing rolls of coin involves a plastic cylinder container with a lid, sized for the the particular denomination in question. These plastic coin tubes became popular with collectors due to better protection of their coins, better to stack and store, and because the original paper wrapper may have became damaged or deteriorated, and the coins needed a safer home.

However, some of the earlier plastic coin holders where made of inferior material, and would shrink around the coins making their removal difficult without first damaging the coins. I have, on several occasions, acquired coins stuck in these plastic holders, and it takes much time, patients and TLC to remove the coins without damaging them.
Plus, some coin rolls where made of PVC and most collectors know about PVC film on a coins surface. It looks green amd is sticky. It will damage a coin if not removed in time, and only an experienced and well informed collector should attempt to remove this film. However, thanks to modern technology and chemistry, coin collectors no longer have to worry about their coins suffering damage inside their holders. Manufactorers now make coin holders that are non-plastisized and made of mylar that do not react with the coin metal or cause them damage.
