Does anyone know what this is?

This is one of the charms I received in my last shipment and I can not for the life of me figure out what is would represent. 3? 3 what? Maybe 3 of whatever you want? 3 kids? 3 years old? 3rd year of college? I just don't know. And especially because it is in the shape of a shield. The coloring? I can't help but think that it is awesome if you know what it is supposed to represent. LOL Please...if you have any ideas? Let me know what you think. If you don't know could you post it to your Facebook page? I am sure someone out there knows what it is! Thank you so much.
