The P mint mark is relatively new on Philadelphia coins. Prior to 1979 the only coins that carried it were so-called "war nickels" minted during WWII. All other Philadelphia coins were said to be plain; i.e. they didn't have mint marks.
The Mint changed its policies in 1979-80 to add the P mint mark to all denominations except pennies. $1 coins were the first, starting in 1978. The other denominations followed in 1980.
Locations are:
Philadelphia cents still don't carry mint marks. This policy was adopted because during times of heavy demand cents may be struck at San Francisco or West Point, but in comparatively small quantities. The Mint didn't want these coins to become instant rarities, so they're indistinguishable from Philadelphia coins.
US coins minted before 1979-1981 (the exact date varies with the coin) don't necessarily have a mint mark. Coins without a mint mark were minted at the US Mint facility in Philadelphia. Since 1981, all coins except for the US cent will have a mint mark; for Philadelphia it will be a "P". US cents, often misnamed "pennies," minted in Philadelphia still do not carry a mint mark even through 2007.
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.
The mint mark "S" on US coins means the coin was minted in San Francisco, California. For more information concerning mint marks visit the site at the related link, below. Coins produced at the Denver mint have a "D" and those at the Philadelphia mint have either no mint mark (for pennies and coins before 1980) or a "P" for all other denominations. Coins produced at the mint at West Point, NY (largely bullion coins, although some 1996 dimes were produced there) have a "W" mint mark.
A mint mark on any coin (not just the United States) indicates where a coin was minted. For modern US coins, P stands for Philadelphia, D is Denver, and S is San Francisco.

Not at all. Denver-mint coins always carry a D mint mark. You're thinking of coins made in Philadelphia, which generally did not have a P mint mark until 1980. The exceptions for Philadelphia coins are: > 1942-1945 "war nickels" have a P > 1979 $1 coins have a P > Cents made in Philadelphia don't have a mint mark, regardless of their date.
Not strictly, because that's really 2 different questions in one. The New Orleans Mint used an O mint mark from 1838 to 1861 and 1879 to 1909, and the first coins to carry a P mint mark were "war nickels" minted from 1942 to 1945, so the O mint mark definitely precedes the P mint mark. Because the Philadelphia Mint had been striking coins without using a P mint mark beginning in 1793, coins from that city can easily predate coins from New Orleans.
I'm assuming you mean the mint-mark? The mint-mark shows which branch of the US mint created the coins, if there is a P mark (or no mintmark on some coins) the coin was minted in Philadelphia, a D mark signifies Denver, an S mark shows the coin was from San Fransisco and a W mark is from the West Point Mint.
The Mint Mark on a US coin is the letter that indicates which mint struck the coin. You'll find the mint mark just under the date:Philadelphia (no mint mark)Denver (D)San Francisco (S)Mint mark are present on many coins, not just wheat cents. In fact, since 1980, all US coins except cents made in Philadelphia carry mint marks. "P" designates other coins made in that city, and "W" is used on special collectors' coins made at West Point.

Check that coin again. No coins that year contain a mint mark, nor did the P mint mark appear on dimes until 1980.

No. In fact, huge numbers of older US coins don't have mint marks. For almost 180 years the Philadelphia mint didn't put a mint mark on any coins struck there. The only exceptions were the "war nickels" made from 1942 to 1945. Starting in 1979, a "P" mint mark was added to $1 coins, and the next year it appeared on all other denominations except the cent. Cents minted at Philadelphia still don't have mint marks.
