This half dollar expanded shell is precision and well-made. The difference between this, and a standard shell is that it has a steel shim inserted inside so that it can be attracted by a magnet. This makes it perfect for unbelievable hands-off changes using tools such as the Raven.
Compared with regular expanded shell, this shell covers all of the coin, hiding a half dollar of the coin inside! It is undetectable.
Include a shimmed expanded shell.
