A mint state coin is an ordinary coin struck for circulation, but it hasn't yet been sent to a bank or put into commerce. It may have a few "bag marks" due to banging up against other coins when minted or put into distribution bags, but other than that hasn't been handled by anyone or suffered any other wear.
Proof coins are specially struck for collectors. The U.S. Mint's description is
"a specially produced coin made from highly polished planchets and dies and often struck twice to accent the design".
Proof coins are handled individually by people wearing protective gloves and are packed in sonically-sealed plastic holders to prevent damage.
The difference is in the 'S' mint mark which is found on the left side of the coin just above her shoulder. The Type 1 dollar's 'S' is like a blob - it is not well defined and is somewhat fat. On the other hand, the 'S' on the Type 2 dollar is more clearly defined and is clearly an 'S'. The Type 2 dollar is much more scarce than the Type 1 dollar.

A mint set contains uncirculated coins from a specific mint in a specific year. Proof coins are specially made for collectors, minted with a higher quality finish, even mirror-like on some surfaces. Currently in the U.S., mint sets are available from Philadelphia and Denver, while proof coins are minted in San Francisco.
A 1999 US Mint 50 State Quarters Proof Set is worth about five US dollars. However, a 1999-2008 US Mint 50 State Quarters Proof Set is worth about 100 US dollars.
A proof grade can not be given to a uncirculated (Mint state) coin. The term Proof is actually refers to a method of manufacturing, not a grade. But proof coins are identified by the by a prefix of PF before the grade and mint state are MS
Special mint sets were produced in 1965, 1966 and 1967. You are probably refering to the uncirculated mint set produced by the mint as a collector set for most years since 1947. The difference between a proof set and a mint set is this; the proof coin is struck with specially prepared dies that are polished and free from nicks and scratches. This gives the coin a mirror like appearance. Coins in a mint set are just everyday coins struck for circulation but are packaged for sale to collectors as examples of the coins minted that year. In 1961 they minted a proof set which consisted of a 5 coin proof set and and a mint set which consisted of two 5 coin uncirculated sets with one from the denver mint and one from the philadelphia mint.
The main difference between mint and peppermint is that peppermint is a specific type of mint. Peppermint has a stronger flavor and aroma compared to other types of mint, such as spearmint.
With both the 1966 Australian "Proof" and "Mint" sets, sets labelled "Commonwealth of Australia" include 5, 10 and 20 cent coins minted at the Royal Mint London. With sets labelled "Royal Australian Mint", all coins were minted at the Royal Australian Mint Canberra.
The 1990 Eisenhower Commemorative Dollar was issued in proof and in mint state condition. The value of each of them ranges between $20 - $30.
Most likely, if you found the (presidential or Sacajawea) coin in change, it is simply in mint state (or more likely about uncirculated). If your coin has an "S" mintmark, it is proof because I don't believe that the San Fransisco mint makes non-proof coinage. If your coin has a "P" or "D" mintmark it is not proof but simply just in mint state or about uncirculated. If you have a silver eagle dollar (the coin is much larger than a presidential dollar) dated 2011, it is uncirculated because at the time of writing, proof 2011 silver eagles have not been released yet.
The very distinct difference is that if it doesn't have a mint mark it was struck in Philadelphia. The P mint mark wasn't used on dimes until 1980. If it has a D mint mark it was made in Denver. Both are only worth 10¢ if found in change. If it has an S it's a proof dime struck at San Francisco and only sold to collectors.
The main difference between mint and peppermint extract is the type of mint used. Mint extract is made from a variety of mint plants, while peppermint extract specifically comes from the peppermint plant. Peppermint extract has a stronger and more intense flavor compared to mint extract.
Mint State - Same as Uncirculated. A coin free of any trace of wear. Proofs - Coins struck for collectors using specially polished dies.
Uncirculated coins go through the normal minting process, but are then removed and placed into sets for collectors. Proof coins are made on specialized dies to achieve better detail and more shine in the finish.
