Hi Pete,
Thank you for your reply. Actually it does has a bit of an egg smell when rubbed, I'd never heard of that before. Also, after I took the pics, I dipped it in silver cleaner (before remembering that they say on tv not to clean stuff). The end I dipped came out bright as could be.
I found it in my own backyard. I am located just a few blocks from where Civil War soldiers camped. No clue if this has anything to do with that or not.
Happy hunting,
Dee
