There are uncirculated sets and proof sets, and they're not the same. Uncirculated sets consist of a set of coins from Philadelphia and Denver, taken from normal strikes. Proof coins are made in San Francisco and are specially struck on mirror-like blanks.
If you have an uncirculated set, as of 12/2008 Numismedia quotes the fair market value (FMV) at $8.00. A set of cupronickel clad proofs is worth $6.00, and a set of silver proofs is worth $26.00
As of 11/2008, retail prices are in the $10 range.
Issue price was $5.00 current retail is $6.00.

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)
These coins are no longer in circulation, but unless they are part of a Proof or Uncirculated mint set or are individual Proof or Uncirculated coins and in absolute mint condition, they are worth 2 cents. An Australian 1987 2 cent coin was only ever released as part of a Mint set. An Australian 1987 bronze 2 cent coin (Elizabeth II)(Proof), uncirculated and in absolute mint condition could fetch up to $5 AUD. A reputable coin dealer will be able to give a more accurate valuation.
Proof and uncirculated coins are valued the same at $15.00
These coins have only just been released into circulation so, unless they are part of a Proof or Uncirculated mint set or are individual Proof or Uncirculated coins and in absolute mint condition, they are worth 50 cents.

Current retail values for this coin are $15.00 for the uncirculated coin and $20.00 for the proof coin
The 1976-S Bicentennial 3-piece coin set is worth in proof condition $15-$20. In uncirculated condition, its value is: $17-$20.

A 1973 6 coin Proof set is $9.00. A 13 coin Uncirculated Mint set is $18.00.
8-1-11>>> This coin was issued as Proof and Uncirculated, both types have the same value of $400.00.
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.
You just spend it. Unless you have a coin in a mint-set with an "S" mintmark that is either proof or uncirculated, your coin is worth $1.
If you are asking about the silver one dollar coin. This coin was issued as Proof and Uncirculated, both types have the same average retail value of $24.00.
