Proof isn't a grade; it describes a process by which collectible coins are specially minted using high-pressure presses and highly polished dies, resulting in a very sharp image and mirrorlike surface.

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.
PR is a grading system used for proof coins
The prf means the coin is a proof, proof coins are not intended for circulation and have mirror like fields (spaces where there is no design) and generally frosty designs. US coins are graded on a scale from 1-70 with 1 being barely readable and 70 being absolute perfection. Prf 65 is a fairly low grade for a US proof made recently. For older coins Prf 65-66 are typical due to damage from improper storage. But for newer proofs, prf 68 is low and 69 and 70s are common.
DCAM stands for Deep Cameo and is reserved for proof coins
The designation "PF" for any coin means it's a Proof coin. Proof coins are given a grade from PF60 to PF70.
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.

I think you mean VF, this is the grade of Very Fine.
pf means proof! and 69 is the grade. grade from 1-70.
If you mean the 1856 Flying Eagle small cent coins? Proof coins were also struck. It's believed that a total of no more than 3,000 coins (including proof's) were produced. Most of the coins were business strikes.
It is the highest grade of proof coin
It stands for proof, proof coins are coins that are struck with great care, are struck multiple times to make things stand out, and are generally higher quality. These coins are sold to collectors at a premium over face value. Some proof coins are made out of precious metals such as silver even though regular strike coins do not use silver.
