Hello, Help Gold Coin

Can you read any inscription on the coin?
If this is bigger than a quarter, yet weighing 4-6 grams, this approaches the weight of a silver quarter.
Wouldn't a gold coin of this diameter weigh a lot more, like 15+ grams?

Thank you DVCollector, and jbuck.
I decided to pull the coin out and look at it again.
I come to realize the coin is the same size as a quarter.
I plan on weighing it again as soon as I get my digital jewelry scale back from a person.
Looking with a coin magnifying glass I cant make out much at all if anything. Not that coin is worn smooth but the opposite and has texture and might say something but I cant read it. There are two puzzling tiny little spots appearing on the coin that look like a little green gem and a little blue gem. Maybe even on more little green gem. I am not sure but it could be something else after all I found the coin under two inches of soil. Looking at the coin again to it still has a gold tone to it but a little less shiny then when after I found it and cleaned it in vinegar a couple years ago.
These are some old pics I took a while back.

Notice the coin is bent and has an indention of what looks like a bullet tried to co through it.

Weigh it to make sure its gold.

Silver quarters issued from 1873 to 1964 weighed 6.25 gm when new. They were struck in an alloy of 90% silver and 10% copper.

Maybe it is a quarter? If it contained 10% copper that could explain the green little color dots and distortion of coin after being buried probably 70 plus years.

Still, thinking but it sure shines like gold. I want gold darn it.
