That's King George I of England on the front of this coin, and Rosa Americana, Utile Dulci (American rose, useful and pleasant) on the back. These are coins that were issued as early coinage to be used in the American colonies, but the colonists did not like them and refused to use them. Today they are sought as collectibles and come under the broad heading of 'US Colonial Coins'.
The Rosa coinage was issued in three denominations: half penny, penny, and twopence. A crowned rose appears on some of the designs.
Olive-gold and walnut-brown toning embraces this unmarked and sharply defined AU58 rarity. This is a near mint state example and a great value in early Americana.
