I ran the Vaquero around parts of the front yard this morning that was shielded from the misty rain. Along with a few chunks of iron and a 1920s shot shell base I found this clasp. It appears to be mother of pearl but very worn from years buried in the sandy soil. It's intact except for the delicate white areas. On the back of each side are double rings where it might have been fastened to a garment with long straight pins. I was down fairly deep in a spot I've passed over with the Compadre a number of times. The Vaquero gave a very weak but repeatable signal so I dug the spot.
