2 that's that not in the videos. I have been looking at videos. They don't tell you about masking. All so from the 1960s and back people did good to make $50 a week and they didn't give the kids money to lose. Where I hunt has a lot of trash. Try putting a silver coin at 4 in. Then put some rust over it then a old rusty nail then lead paint chips and then put a pipe on top and cover the hole. No detector will find the coin. You need to dig the trash out first. My wife and I went to a old house we dug over $8 dollars of penny's and other clad out then we found 12 mercury. Dimes. The videos help but you have to do the work
