    The same image on both sides. This is a true hand full of metal. It looks great on the web site and is even better in my hand. Thanks guys. I will be taking this to the next legion meeting. My post is the only Navy/ Marines/Coast Guard post (Furniture City Post 258 – Grand Rapids, MI) and we have a large number of Shellbacks. I also am the proud owner of one of the Gator Navy coins too. My collection grows.

      Hi Brian, thanks for your feedback! We’re actually working on plans to make both US Navy uniform belt buckles as well as some “Texas” sized ones as well.
