Hi Silver. Maybe the dopey thief snatched it thinking it was a real gold half guinea, then threw it away when he found it wasn't. Didn't some idiot do that at the Melbourne museum with a copy of a huge nugget they had on display in a window. I think it may have been the Hand of Faith. Smashed the window, took off with the copy, then dropped it not far away when, maybe, he thought it was a bit lighter than a gold nugget should be. DOH! wiley.
