That is a really nice little piece of US historical Silver Coinage...
Be careful about cleaning your finds in anyway!
This 1847 you found would be worth a million to me, because you don't find to many seated coins at the beach, but it's a high mintage date with a G-VG grade.
No harm no foul cleaning it up.
If you come across any more seated coins you should check dates and mint marks before any cleaning.
They could be valuable and damaged by trying to clean them up.
