Historical Artifacts (Sandy Hook, CT)

Hello! I am a history major looking to add to my collection of historical artifacts. The era or item doesn't really matter to me as long as it is an authentic piece. (a certificate of authenticity is a nice bonus). If you have anything you wouldn't mind parting with, hit me up and we'll discuss! I'll take anything from coins or medals to war bombs, propaganda posters and everything else you can think of! Thank you for your time!
