Dorry, the Avatar is one of my finds, yes it has been one of my hobbies for over 25 years, and luckily I live in an area where colonial era artifacts are found......The Avatar is a 1787 New Jersey Colonial Copper. After America won their Independence, we were still using British/French Coppers and Spanish Reales for our transactions, afteall there was no US MINT yet, so a few states were authorized to produce their own legal tender hard cash. NJ,NY,VT,CT and MASS were the biggest producers.
Oh NJ Coppers were worth 1/15 of a Shilling back then.

The NJ coins were made in 1786, 1787 and 1788 and are very collectible.

BTW, I used Hydrogen Peroxide to clean copper coins and brass buttons.

Jyes
