Need help identifying this rock that my grandfather found in or around Hot Springs, AR 75 years ago. PLEASE I inherited this from my grandfather and all i know is that it's very heavy and it appears to have gold content. It's actually just been sitting around my house as a door prop the past 20 plus years. help?
From the looks of it, I would suggest that it is more likely pyrite than gold. However, it is difficult to say without inspecting it in person.
