The "S" and the "D" are called mint marks which identify which US Mint produced the coin. Coins with no mint mark prior to 1980 were minted at Philadelphia. Just having an "S" or a "D" mint mark does not mean the coin is worth more. The value of a coin is generally determined by the demand collectors and investors have for the coin. The more people who want to own it, the more it is worth.
For example, a 1943 & a 1943-D coin in MS60 condition are worth: $5.00. A 1943-S coin in the same condition is worth: $15.00.
If the pennies are brand new (like grandpa got them from a bank and socked them away) you can get several dollars for them depending on date and mintmark. If they are just pennies taken from circulation they typically run at most 2 cents each. One big exception is the 1931 S . Even worn it could be worth over $50. You might also get a dollar or so for a worn 1931 D and 1933 D .
legally they are still worth 1 cent. but since before 1982 pennies were made of pure copper they may be worth a few cents more. i wouldn't try selling it though
1980-S pennies were only issued in proof sets. At a minimum, they are worth about 75 cents. The highest grade proof condition pennies are worth $4.00 and up.
1909-S-vdb, 1914-D, 1931-S and others.
Usually S mintmark wheat pennies are worth more.
All wheat pennies, regardless of year are worth at least 3 cents if the date is readable. Some wheat pennies though, are worth quite a bit more. For instance, the 1909 S VDB penny is worth several hundred dollars even in worn condition and so is the 1914 D penny. However, a 1909 S VDB penny in pristine condition could be worth thousands of dollars. In general, the older the wheat penny the more valuable it is. For example, most wheat pennies dated in the 1940s-1950s aren't that valuable, but wheat pennies dated in the teens and twenties are worth a lot more.
5 to 10 cents a piece if circulated at all, about $1-2 if uncirculated.
For example, a 1943 & a 1943-D coin in MS60 condition are worth: $5.00. A 1943-S coin in the same condition is worth: $15.00.
In most years the San Francisco Mint turned out fewer cents than Denver or Philadelphia, so many are more expensive than the others from the same date, but not all are. You certainly cannot say that any S-mint cent is worth more than any D-mint.
Steel pennies were only minted in 1943. If the penny you have is really a 1944 and is steel it is worth a couple thousand. If however it is really a 1943 it is worth .05 to 1.50 depending on condition. If it has no mintmark and is uncirculated it is worth $12.00. If it has a D and is uncirculated it is worth $15.00. If it has a S and is uncirculated it is worth $25.00. The mintmark is located below the date.

Not all that much. Most of them in circulated condition are worth about 3 cents from the 1940s-1958 (last year for wheat pennies was 1958). Though error coins and high grade examples will be worth more.
Well, if it just says 1909 without a S, D, or VDB on it, then its probably around 5-20 cents. The reason for that is because there was 72.7 million pennies that was minted in 1909 (without S, D, or VDB mark) and pennies that are worth alot have around 0 to 2 million pennies minted in that year.

A 1943 copper penny is known to be worth a lot of money,
Only around 5-10 cents each. They're not as valuable as most people believe.
