Treasure of Sierra Madre - Walter Huston's happy dance Dug up a roundish whatev while planting some Icelandic Heather in my front garden originally thought it was a Revolution War era iron mortar round - pitted and rusty charcoal colored and quite heavy for its golf ball size. When I threw it toward my garden cart I missed and it bounced on the concrete walkway and split open.
Had it tested by a Penn State mining tech and it's pure gold!!! At most 0.75g if properly smelted out, but then she said there's an approx 10-15% waste in contemporary smelting ops - so what I actually have is "a really cool paperweight"
