Did a short hunt this evening in the park where I found the seated quarter last weekend. First good hit was this IH Cent (1902). Got a couple of wheaties (1913, 1941, & 1958 ) and this thing that seems to be made of lead, although there's no white patina -- could it be pewter???). Notice the rings on it. The back is caved in and after cleaning it with my GemOro ultrasonic cleaner, it's quite pitted and appears to be kinda old. Any ideas?
