Started off slow: a lot of rusty tin surrounded by broken glass, crockery, etc. Finally found a few neat items: horseshoe, square nails, electrical insulating “knob”, a buckle and a protractor to name a few. The protractor is not ferrous and has a green patina. I’d guess copper. It is very thin; amazing that it wasn’t mangled. The buckle is non-ferrous also. I’d guess brass. The license plate is 15-1/2” long. I can’t read the year. No real value but I really enjoy the history of the property.
