In coin grading terminology "MS" stands for "mint state" or the state a coin is in when minted and uncirculated. Showing no signs of wear or indication of circulation. MS is interchangeable with "uncirculated". Although MS coins have no wear from circulation they may have varying imperfections from the minting process. To allow for that, the "MS" coins are graded on a scale beginning with 60 and going up to 70 (this is the highest number, which indicates supposed "perfection"). So MS66 would mean a "mint state" or uncirculated coin graded 66 out of a possible 70 on the grading scale. A very nice coin.
"PL" in coin grading means "prooflike". It is used to describe a coin that has mirror fields and fine details resembling a proof struck coin but is not a true proof.
VG-8 means "Very Good" and scores an 8 on a scale from 1 being barely recognizable to 70 being absolute perfection. Coins grading VG-8 are usually very worn, but most of the text on the coin is still readable.

Raw refers to a coin that isn't sold in a case. Higher end coins are usually encapsulated and graded by a coin grading company such as PGS. A raw coin however isn't. Some people may try to assign numeric grades to a raw coin, however until it is graded by a reputable grading company, that number is only a rough estimate and most likely is going to be different than the coin if graded by a grading company.
PCGS stands for Professional Coin Grading Service, one of the most popular commercial services that grades coins. See www.pgcs.com for more info.
Coins are graded to their condition that includes the amount of wear it has. MS68 is a level of the grading used in coins. It is a very high rating, MS means Mint State which means uncirculated condition, straight off the mint's stamping die. 68 is a level of mint state, the higher the number the better the condition. Professional grading societies exist to grade coins they can tell the difference between a 68, 67 and a 69 mint state coin. Hope this helps you.
