Is there an increased value on a 1940 walking liberty half dollar if when you turn the coin over the eagle is upside down?

Answer 1

Please compare your coin's orientation with any other U.S. coin in your pocket change. All U.S. coins have their reverse sides oriented opposite to the front. That is, if you flip it side to side like the page of a book the image on the back will be upside down in relation to the image on the front.

The U.S. is one of the few countries to use this orientation. Most major countries (Canada, U.K., EU, Australia, etc.) issue coins with both sides oriented the same direction, so a lot of confusion can and does occur.

On the other hand, if you flip the coin side to side and both images point the same direction you may have what's called a rotated-die error. You'll need to have the coin inspected in person to determine if it's genuine, because rotated die errors can be worth a definite premium.
