Stehviesue,,
Welcome to TNet from Ohio,
Nice find but I have to agree with pepperj, looks like a coat jacket button. From your profile I see you live in central PA, you are right in the middle of some of the best detecting locations our country has to offer. Recommend you look into joining a local metal detecting club or find a more experienced detectorist to hunt with. Additionally recommend you learn everything there is to know about your machine. Both recommendations will pay big dividends as you learn our great hobby. Good luck with your hunts and again, welcome to the best detecting site on the net. V/R Walt
