Up until last night I have only dug 2 Big Coppers.I got to a permission site and within 10 minutes I get a great signal.I have no idea how old this spot is except its on 1872 map.I immediately find out its much older when an 1847 LC pops out.5 minutes later an 1851 LC!10 min later I see no date LC on top!Unbelievable hunt I will always remember!
