A Proof coin is a particular issue of a coin not a grade of condition.
The grade of a circulated coin is based oc how much wear it has.
It means "premium quality". It is not an official form of grading.
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.
The best thing to do is send it to a third party grading service. They will grade the coin for a fee. This will give you an accurate grade of the coin. You can also take it to a coin collector or use a free online guide like PCGS.
AU55 NGC is a coin grading designation provided by the Numismatic Guaranty Corporation (NGC) which signifies that the coin has been graded as Almost Uncirculated (AU) with a numerical grade of 55. This indicates that the coin has some wear but the original details are still visible. It falls between AU50 (less wear) and AU58 (more wear).
PF-69 is not a value, it's a grade. But it does affect the value, the higher the grade the more value a coin has. A PF-69 coin is one grade below a "Perfect" proof coin.

If you mean a US 1848 Seated Liberty dollar, low grade coins are valued at $300.00-$500.00 better grade are $700.00-$1,000.00 and up. I suggest having a dealer or collector grade the coin for a better idea of value.
