Yep!!! A WW2 era slot broach US Army Good Conduct Medal...
As Rob said, a nice ww2 era GCM. Nice little medals that are still very available.
There are plenty of other awards to keep your interest now that you have this one. Don't forget the campaign medals, victory medal, purple heart etc... Good pick up, and thanks for sharing!
If you like the maker hunt, you can get into the CIBs and jump wings too!
And don't forget...they need to live in their black leather cases too!
