Is A Proof The Same As Perfect? .

no

I don't collect modern proofs.
Neither do have the resources needed to collect the perfect proof of the age and class as described below:-

Over 100 years ago, and up to about the 1950's at most Mints, proof coins were used by mints as a form of quality control.
A best quality planchet was used to strike, at optimum pressure, a prime example of a coin intended for issue. Neither the blanks nor the fields of the dies were polished, and the coin relief detail was not cameoed. Only a handful were needed, to act as examples of a perfectly struck coin, they were kept in house at the Mint, and were never issued to collectors.

If, when they had effectively served their purpose, they were most often released into circulation, to be lost to collectors forever. They were not necessarily kept in ideal storage conditions. Very few of this class of proof coin were ever retained, and thus are extremely rare and valuable today. Gold coins tend to be the strongest survivors, due to their resistance to tarnishing, and thus are the most common of the three coinage metals today.

It was only after about 1960, that most Mints around the World started producing mirror field cameo relief proofs specifically for sale in huge numbers to collectors. With this class of proof, there is no need for quality control, which is now achieved by other means.

Sorry, now I see what you are saying. Most of my comm sets are post 1950. I really appreciate your time.

It's important to remember that proof is not a grade, it describes a coin's method of manufacture. Proof coins follow a different process vs. coins struck for circulation.

Today'a modern proof coins are typically struck from specially prepared/polished dies and are often struck on polished planchets. Generally, they are struck two or more times to bring up the full details of the design.

In contrast,coins meant for circulation are generally struck just once on unpolished planchets;they may or may not have full design details.

As noted above, proof coins are struck specifically for collectors and are sold at a strong premium.

A proof coin graded as a "70" is about as perfect as can be produced; same for a mint state (MS) 70 coin.

Basically to answer your question is NO.

to the CCF!

As commems and others have said above, the term Proof refers to the process by which the coin was made. This involves special polished dies, polished planchet and a different, slow striking process. While a "perfect" proof should grade PR-70, an impaired proof can grade as low as PR-01. Wear on a proof doesn't change the fact that it was produced as a proof, but the fact that it was produced as a proof may become impossible to recognize. A circulation strike may grade MS-70, but it can never cross over into a proof.

I didn't know that the Ten Commandments were slabbed.

Which TPG slabbed them?
