I seem to find most $1 $2 coins 1 to 3 inches down! Today tried a new park found junk and an earing! A lot of what i thought was a $2 coin came out as a lot of old 1980 style drink tops but 6 inches + deep! So what is the average depth of a $2 coin! Or how deep is too deep? I have found 1c 2c 5c ets deep! Also did our local rugby club 6am this morning, could not belive the amout of beer pull tabs and bottle tops, did not even dig one plug, my detector was screaming its head off in junk. Cheers
