It's often best to start with a photo of what you actually claim to have as opposed to posting one that appears to have been found online. I assume you've taken the time to research this on your own and, perhaps, were unable to come up with anything suitable?
Just dont have a pic yet and am not home at the moment but uts this exact medal The back is actually engraved to a mr a l.ponsford bank of america milan italy 1951
Let's say you were interested in buying a car, so I showed you a photo taken from some website of a car, claiming I had the same one, and asked you to place a value on it. Would you do so, or would you want to see photos of the actual car? I realize most non-coin people fail to understand the importance of this, but being able to see exactly what you have is often paramount, especially when "value" or "worth" is desired. Your best bet is likely to wait until you return home and can post photos of your actual find.
