thinking about getting a metal detector , I collect old U.S. COINS , complete jefferson nickels 38-now , Ike dollars 71-78 , Indian head cent , statehood quarters 99-09 , native american dollars 00-11 , lincoln cent 1909 - 2011 ,buffalo nickels , presidental dollars , roosevelt dime 46-11, and parks quarters. So a metal detector would be very helpful , I've found some old coins w/out detector. so i'm ready to invest it one soon
