I found this piece at a place I frequent. It rang up as a solid 72 on my MX Sport, which is in silver dime range. No apparent silver marks. I tested it with a silver acid test kit, and it didn't change colors. You can see to the right of the acid spot where I did first test. It left a dull milk color. I am not sure, but could this be silver? Did I conduct testing correctly? The opposite side shows to the left a copper color, but that is just lighting. It has silver coloring throughout. This surely an odd piece to me. I have no clue what it may be. The old home site was built in the late 1700's and occupied up until early 2000.
