I've been metal detecting on our property for the past few weeks. I have cleaned up lots garbage and these are the items I've kept. I know there's nothing of value but is there anything that's from the 1800s or older? They're were a few square nails that look really interesting. The cross is really lightweight and I'm thinking this is probably pretty obvious that it's not very old...or maybe it is? I have no idea what the big thing is, anyone know? I've read there's no way to tell how old get new the bullets and casings are. Then there's a belt buckle? Any thoughts if this could be very? It has a cross on it but it's not easy to see. It will fuel my flame if there's anything that shows life from the 1800s. On our property (in michigan) we have a house that was a one room school house. The school house was originally built sometime in the 1800s, burned down around 1900, then rebuilt in the same location. We have a creek through our back yard and there was a gristmill on or near our property (on plat maps). There was was also a post office and store on the property next to us (now there's nothing there). There's still lots of land to check out. Any ideas on any of this recommendations going forward? I appreciate your help!
