Coins are made by striking a blank in a press and then ejecting it.
Sometimes the ejection fails and it gets struck again. In many cases the coin moves a bit so it receives a double image.
Double-struck coins are popular among collectors of error coins and can sometimes bring significant prices.
Error coins need to be seen for an accurate assessment, take to a coin dealer.Also please note that coins are said to be struck rather than "stamped".
Proof coins are coins that are prepared on special blanks, struck twice or more to really have great detail, are usually hand-inspected and then placed in special cases for collectors. Proof coins are so shiny that you could use them as a mirror on the parts that don't have a design on them. Usually proof coins sell for much more than their circulation counterparts. Some proofs are struck in precious metal that circulation coins aren't struck in (since 1992, the US has struck both "clad" copper-nickel proofs, and 90% silver proofs).
A proof coin is made from a highly polished planchet (blank) and struck twice to produce a highly detailed relief. Proof coins are not put into general circulation.
Proof-like coins have features similar to a proof coin, but may not fit the definition of a proof (for example, they may not be double struck). Proof-like coins have mirrored fields (you should be able to see your reflection in the spots of the coin where there is no design) and are generally of higher quality than coins produced for circulation.

Sometimes, for various reasons, the die used to make the coin has a double image on it and thus, shows on all of the coins struck by it. In other instances worn machines will cause the die to "bounce" when it strikes the coin blank leaving a slight double image call "machine doubling".

It stands for proof, proof coins are coins that are struck with great care, are struck multiple times to make things stand out, and are generally higher quality. These coins are sold to collectors at a premium over face value. Some proof coins are made out of precious metals such as silver even though regular strike coins do not use silver.
