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).
The January 2010 edition of CoinAge magazine values the 1958 US proof set at $52.00. That same magazine, however, has four advertisments offering to sell such a proof set (each with different Tax and Shipping & Handling charges) at $42.00, $49.00, $51.50 and $52.25.

The answer depends on the region whose cents youare talking about. US coinage, for example, is different from Eurozone coinage.The answer depends on the region whose cents youare talking about.

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.
Matte proof coins are special proofs that have a grainy "sandblasted" look on the surface. Matte proof coins were sometimes made in the early part of the 1900's. Normal proof coins have a mirror like brilliant surface.

You may have an uncirculated coin, but not a proof. Proof sets were discontinued in 1942 due to WWII. Proof coinage wasn't resumed until 1950.Please see the Related Question for more information.
Yes. Proof sets contain official US coinage that can be used as legal tender, although to a collector proof sets are worth more in the mint holders in which they are issued. Proof coins are not intended to be spent, but are legal US tender.
No. Coinage of proof sets was suspended during WWII and didn't resume until 1950.
There is no record of the Royal Mint having produced a "gold" Proof set in 1974, only the usual Proof set. Royal Mint gold Proof sets issued from 1980 contain only the "Sovereign" coinage.
There are no British general circulation decimal coins that could be considered to have any collector value unless they are "Mint Uncirculated", "Proof", or part of a "Mint" or "Proof" coin set.
Depending on context, currency, coin, money, coinage, piece.
If all coins have birds on reverse, it is a BVI proof set. Average retail value is $12.50.
The San Francisco Mint was placed on hold in 1955 and did not resume production until 1968 when it began the production of proof coinage and only produced supplemental coinage from 1968 until 1974. Since then it only produces proof coinage except for the Susan B. Anthony dollar with 'S' mintmark from 1979 until 1981 a portion of the 1980's pennies were produced there but bear no mintmark. No circulating 'State' quarters are produced in San Francisco.
That is far too broad a question to be answered here. The Isle of Man section of the World Coins catalogue devotes about 60 pages to Isle of Man coins, the majority of which are Proof.
Proof coins were struck to check the quality of the dies used for stamping the coins. They were "experimental" and often were not put into circulation. More recently, though, central banks (or mints) have discovered that there is a lucrative market from collectors and so many sets of proof coins are produced, not for circulation but simply for numismatists.
