Many countries issue proof-quality coins in varieties much greater than those minted for ordinary circulation. For example, the US strikes proof-versions of its 6 circulating denominations but in addition makes many bullion, commemorative, and other collector-only coins in proof quality as well.
A Proof is a coin produced by a mint to show what coins were in circulation at that point in time. For example, a given year will produce a proof set. The proof set is to show the highest quality of the coins at the time. The original proof sets are worth many times their stated face value. In modern times proof sets are mostly a numismatic (coin collector) interest. You can see examples of proofs by looking up the US mint on the web or by paying a visit to ebay. Note that proof also is a slang for the quality of a coin. Proof coins are (Im not an expert but) in my mind a MS 65 (coin grade 1 - 70)
A proof coin is a specially minted coin that is produced with a higher quality finish and detail than standard circulation coins. Proof coins are often generated for collectors and have a mirror-like surface, frosted designs, and are typically struck multiple times to enhance the level of detail. They are frequently sold in special packaging and are considered more valuable than regular coins.
The term Proof actually refers to a method of manufacturing that produces coins with very sharp details and a mirrorlike surfaces and are called Proof coins. Uncirculated or Mint State coins are coins not released into circulation and have no wear on them.
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.
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.

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.

Coins in proof sets are generally worth a bit more than coins used in general circulation.
Proof coins are special coins produced by mints with special dies and polishing to be perfect and to have an extra eye appeal. Thus proof coins are near perfect representations of that particular coin.
Satin proof coins had a dull luster to them and looked too much like uncirculated business strike coins so they changed to the brilliant proof coins.

A satin finish on a proof coin gives the field a softer appearance and not the crisp mirror finish found on other proof coins.

No these are proof coins, but some proof coins do show up in pocket change..
Proof coins have a very high quality finish with a mirror like surface. They are sold in year sets, or very occasionally as individual coins. The packaging they are sold in will have all details of the coins inside, including the fact that they are Proof coins.
The 1970 proof penny, as with all modern proof coins, was struck in the same manner as regular business coins ( those intended for circulation ) except the dies used for proof coins are highly polished to produce the mirror like surface on the coin. Also, the proof coin is struck multiple times to bring out the finest detail of the coins' design whereas business coins are struck only once.
The U.S. Mint does not assign grades to any coins it sells. But Proof and Uncirculated coins do have different grades.
