[QUOTE="navieko, post: 507292, member: 988"] Hi, any idea what these could be? Found while detecting with SDC 2300, they sounded off like gold/lead. Quite heavy for their size. Larger one 2.43g, smaller one 0.84g (feels about the same weight I'd expect lead or even gold to weigh for their size). Tried holding a flame to the smaller one to see if it'd melt to indicate lead, and after a few seconds a fragment of outer "crust" popped right off to expose a very shiny/metallic inner core. Hard to tell from the pics but under microscope the exposed metal almost looks to have tiny crystalline features (looks a bit like platinum).
