The picture shows a view of this 1939 New York World's Fair Advertising Souvenir Elongated Cent. The obverse has a raised image of the Trylon and Perisphere and the reverse has been flattened as made. It would have been made from a wheat back Lincoln penny. There is a hole as made to hang as a charm or for use as a key chain fob. It reads as follows:
NEW YORK WORLD'S FAIR 1939 THE WORLD OF TOMORROW
The penny measures 3/4'' x 1-1/2''. It is in excellent condition as pictured.
