I have found 2 wedding rings. Made me wonder why but then mine is AWOL currently. I have also found a dead mummified mouse. It was so dead my kitties weren't interested in it. Mud dauber nests are also common for barn stored items. I also found an old shoe hook, for when shoes had buttons on them, in one of the treadles. Lots of old buttons and a .22 rifle shell one time.
