Thanks for the replies guys! Visually - I see what you mean regarding melted aluminium but I think it's probably too heavy. Could very well be copper although I thought it might be greener? I honestly don't know enough about this subject so filing it is a good idea!
Hi all!I found this with my metal detecting pinpointer in a park here in the UK. It was just beneath the soil (about an inch down). I couldn't believe the strength of the signal given how tiny it is (maybe 4mm on the longest side). I initially thought it was iron or lead but after closer inspection - I have absolutely no idea!It's 0.24g, and doesn't react at all to a very strong neodymium magnet. It does however make my pinpointer scream from an inch away! Any ideas?Cheers,John
