So I redeemed a $25 amazon gift card through PO a couple months ago, my second sine July! I used it towards a Tesoro Compadre Metal detector. I found this pretty neat old button. I think it is called a Great Seal button, and they started using them in 1902, but I am not 100% sure on that yet. I have also found tons of used blank ammunition from 1940-1978. There used to be a military training area down the street from where I live, but it is just woods and new house there now. I also found an old musket round ball in the woods, which I thought was pretty cool!
