Astronomical Units (AU) are most useful in describing the distance from a planet to its sun. For just about any other purpose they're either too long (distances on a planet's surface) or too short (distances between stars) to be of much practical use.
Au is the atomic symbol for the element Gold. Au is technically 100% gold, because Au only stands for gold, and no other element.
It is Au, for Aurum.

No, a light year is actually much larger than an astronomical unit (AU). One light year is the distance that light travels in one year, roughly 9.46 trillion kilometers. One AU is the average distance between the Earth and the Sun, about 150 million kilometers.
840 miles = ~0.0000090365521499 AU
1 astronomical unit (AU) is approximately equal to the average distance between the Earth and the Sun, which is about 93 million miles. Therefore, 5.20 AU is approximately 483.6 million miles.

I am assuming that it is an 1852 minted in Philadelphia since the vast majority were. For a certified coin in AU grade the value is between about $250 - $400 depending on what grade AU it is (AU-50, AU-53, AU-55.....).
You didn't state what denomination the coin is, but assuming you're referring to a cent, I'm afraid that you have the much more common issue. While a 1960 Philadelphia small date cent might retail for $2 or so in AU, Denver examples are much more plentiful and go for only 15-25 cents.
