Seems as though folks loose a lot of things. Knives are high on the list, along with silverware. The two metal strips in the center/left are animal ear tags from the 50's, and I believe these were used on cows or pigs. They used aluminum back then, not plastic. These are from my backyard, and bear a phone number, which back then was just 5 digits. The round golden object in the upper left is a dog license from Idaho, which was found in a park here in Medford, OR. The green object ( upper right ) is a small clip on flashlight usually hooked to a key ring. I tried for 20 minutes or so to find the base before I realized that it was still hooked to someone's key ring!
