Hello, Moises --
As you know, your coin is heavily damaged, and this renders value very low. It is not a fully formed cob, and, while the date appears, the denomination and mint mark do not. Overall value is equal to precious metal content. If you sent it to NGC, it would come back un-slabbed.
From your picture, it looks like it is made of gold. That's good. Gold is trading at about $1800 US dollars per troy ounce. There are 31.1 grams in a troy ounce.
