Proof Coins & Proof Sets

Proof coinage
Word: Word Starts with Ends with Definition
A beautiful example of a proof coin. Notice the deep mirror-like reflectivity of the surface and the detail in the strike.
Proof coinage means special early samples of a coin issue, historically made for checking the dies and for archival purposes, but nowadays often struck in greater numbers specially for coin collectors (numismatists).
What is a Proof Coin?
From Susan Headley, former About.com Guide

Low mintages for the Barber Dime, Quarter and Half Dollar assure that no more than 250 sets of U.S. Proof coins of 1909 could ever have been assembled.
Silver Clad Proof Coins
In the 1960s, the US Mint replaced silver coins with silver clad versions. Due to the Coinage Act of 1965, 90 percent silver alloy was no longer in use.
Silver Eagle Proof Coins are considered the coin collector editions as they also have decreased mintages and attractive deep cameo mirrored fields. Complete sets of MS69 and PR69 Silver Eagles are becoming very difficult to put together.
Proof Coins
The grading of Proof coins in higher levels is similar to that of Mint State coins. An absolutely perfect coin can be judged as Proof-70.
Proof coins are graded the same as regular mint issued or business strike coins. Proof coins can receive a circulated coin grade. Typically proof coins receive a condition or grade between 60 to 70.
Proof coins are coins which are specially struck for a variety of purposes - the original purpose, as the name implies, was to prove the die; so the earliest proofs are akin to die trials.
Proof coins have been made to the highest standard. Modern proof coins are produced using the most up to date technology as well as incorporating years old handed down skills.
Proof coins are struck using a specific technique to produce highly-mirrored fields and frosted devices. These coins are generally struck with more force, usually twice, and with polished dies.
Proof coins in the Liberty Head half eagle series dated in the 1840s are so rare that no private collector has ever assembled a set.
Proof coins are struck by technicians who hand feed the blanks into special presses. They are produced, examined, and packaged using extreme quality control. It is very unusual to find major proof errors.
Proof coins are ones struck with greater pressure than the usual circulation issues, using specially polished dies and carefully prepared blanks. In some cases more than one strike is made to ensure that the metal flows fully into the design.
Proof coins were handled much more carefully. Unfortunately, proof surfaces tend to magnify even the lightest mishandling into hairline scratches. Indeed, prooflike uncirculated coins generally have bagmarks and hairlines.
Proof coins are versions of normal coins, but produced by special dies, which give proof coins a mirror-like finish. They are collector's items, and more expensive to buy than the normal versions.
Proof Coins are special coins not made for circulation, but are made as specimen examples for collectors. They are usually struck two or more time with at least twice the normal pressure, generally with specially prepared dies to bring out the detail.
Proof coins are graded numerically in a fashion similiar to Mint State coins except they will be noted with a “PR' instead of an “MS' before the grade. For example, a Gem Proof will be graded PR-65.
Proof coins are graded in a similar manner to business strike coins (i.e. Proof-1 through Proof-70).
Proof coins represent the very best of the minter's art. Today, they are manufactured from hand-polished dies, are virtually flawless and are superby presented in customised packaging, with strict limits on production.
Proof coins have shiny fields and frosted devices (designs) whereas reverse proof coins have frosted fields and shiny devices.
