MS-60 is the lowest mint state on a non circulated coin. The grading goes from 1- 70. 70 being the best a coin can receive in a professional grading scale. Right below MS is the AU 55 or AU 58 which means that it shows just the slightest wear or bag marks. Above MS is PR--66, 67, 68, 69, and 70 being the grades of from nearly perfect to more nearly perfect to PERFECT!
To determine if a coin is MS60 it must be seen. I suggest you take it to a coin shop and have it appraised.
The purity of the compound that the coin consists of.
M means Mint, 60 is a specific number on a scale of 1-70, 70 being the highest. So Mint 60 is a coin with very few flaws, in other words it has a higher value. I believe that you mean MS60. Uncirculated Coins from the mint are designated MS60 - MS70, MS70 being "Perfect". MS 60 is used to say that the coin is uncirculated, usually not professionally graded.
To get that specific of a grade on a coin, it would need to be professionally graded though a service like PGCS, though a coin dealer in a shop could give an approximate grade.
MS stands for mint state, and the rating of 60 is on a 70 point scale.

An MS60 is the lowest of the uncirculated grades. The coin will have no wear but will have marks from other coins touching it and maybe a few light scratches. It may or may not have mint luster. An MS65 is a mid-range uncirculated grade. The coin will have full luster and very few light nicks and scratches.
You have a American Eagle Bullion $10 coin - if minted in the year of 1995, its worth in a MS60 condition is: $ 265. By the way, the coin should be carrying a mint mark of "W."
You have a Liberty Seated Dime - a very popular coin for numismatists (coin collectors). A coin minted in 1868 that is in good condition (G4) is worth: $18.00; if its mint state is MS60, the value rises to: $ 300.00.
The BU designation does not mean much. It is best to have coins professionally graded. That being said, the Carson City silver dollars are a great mint and that is a good year. A "brilliant uncirculated" could mean a variety of grades, but should qualify for at least a MS60 and go up from there. An MS60 can fetch $210.00 and an MS65 can go for $1810.00 so you see, it's best to get the coin "slabbed," or graded by a professional grading service. This will cost about $100.00 and can be done through your local coin shop.
