Uncirculated coins are ordinary coins that were struck for use in commerce but haven't been spent yet and have no wear. Sometimes you can be lucky and get a roll of uncirculated coins from a bank. Most Mints around the world also sell uncirculated coins to collectors; they're in sealed packages with some form of indication that the coins were never spent.
Proof coins are specially struck for collectors. They're made separately from ordinary coins using highly-polished blanks and dies that produce extra-sharp, very detailed images. Many proof coins have mirrorlike surfaces but others receive special treatments that give a "frosted" appearance to the raised parts of the design or the background.
Circulated means the coin has been handled and used. Uncirculated is a coin that hasn't been spent, and is often fresh from a bank roll. Proof is a special strike technique resulting in an extra clean and shiny finish to the coin, and is made specifically for collectors.
A proof coin has a special shiny finish on it and it is made to be sold to collectors, and not used as money.
It would depend on if the coin was released as a proof coin (very shiny and looks mirror like, with an "S" mint mark) or an "uncirculated" coin and the general condition of the coin. A Proof coin, depending on blemishes (or lack there of) and if it is a Type I or Type II, can get between $7 and $65. An uncirculated coin that has never been in someone's pocket, touched or scratched can get between $2 and $750. In any case, if the coin has been touched or damaged, spend it for the face value.
An official "US Mint Set" is a Uncirculated coin set. They have uncirculated examples of every denomination issued from each mint for the year of issue. They are the same.
An "Uncirculated" coin is exactly that. It has never been in circulation and is in mint condition, and in the packaging it was sold in. A "Proof" coin is similar to an "Uncirculated" coin in that it has never been in circulation, but they are made on specially polished dies so that they have a very lustrous and shiny appearance. Proof coins might also be made from a metal other than what the normal coin might be made from, such as gold or silver. Proof coins usually cost a lot more to buy irrespective of what they are made from.

You can't unless you pay the $20+ to send your coin to NGC/PCGs even under magnification the ordinary person cannot tell the difference between a pf69 and pf70 coin. Of course, it is easy to tell if your coin is uncirculated or proof, a proof silver eagle will have very shiny, mirror like fields that are easy to see yourself in. An uncirculated silver eagle will be shiny, but won't be mirror like. Also, the raised part of the coin will look frosted on a proof coin but not on an uncirculated coin.
The American Eagle Gold coins are made in Uncirculated and Proof versions. Circulated means exactly that, it has been circulated and or used. We do not use any gold coins at all in every day business. Proof coins have a highly reflective, mirror-like surface. The surface of a uncirculated coin does not.
If the coin has an "S" mintmark it's Proof, if not, it's the uncirculated version. Current average retail value for a Proof coin is $40.00 Uncirculated is about $29.00.

Nothing, just two different abbreviations for Proof.
Well, an uncirculated one would sell for whatever 1 ounce of silver is selling for, today about $27. However you say with proof, I'm not sure what that means, if you mean it has some sort of certificate of authenticity or it is a proof coin. A proof coin will have mirror like fields (parts of the coin with no design) and an uncirculated coin will have shiny, but not mirror like fields. A proof coin is more expensive and would sell for around $70.
If the coin is a Proof coin it is worth about $20 USD. If it is not a proof coin and is uncirculated it is worth about $12 USD. (2/28/2010)
If it's not a uncirculated or proof collectors coin in the mint package spend it.
In coin collecting, it means Brilliant Uncirculated, a very nice coin, but not as good as a Proof coin.
