I found this coin this past weekend . It was 8"+ deep & hit at 21 on the Nox . It's not a dime . It has a Roman numeral 1 in the center . After looking at US coins smaller than a dime , I'm pretty sure it's a foreign coin . I looked at Mexican coins next since I'm only 350 miles from the Mexican border & at one time Arizona was part of the Mexican territories . I found that a 1883 Mexican One Centavo had a Roman numeral in the center and was slightly smaller than a dime . I checked the diameter and it was right on the money . I'd like to clean it to try & get some more details but I'm a little apprehensive in doing so . Any thoughts on cleaning it & How ?
