I keep everything all but the pull tabs, bottle caps, foil etc. It goes in my pouch to get dumped in the trash can. I leave nothing behind. I will not sell my silver coins, buttons, boy scout pins, civil war bullets etc. but i did sell my silver and gold rings last year i dug up the past 3 years 2013-2015 and bought a Colt AR-15. As for the clad i found? I bought silver coins with it to add to my collection.
I haven't been out yet this year. I will when the doc saids i can stop wearing neck brace. Been wearing it since Feb. and this nicer weather we been having drives me crazy. Happy hunting...
