I got out between the rains that came today, went to a park Found two v nickels 1897 1902 2 Jefferson's a pair of Indians 1898 1894 a small silver ring some wheat's 1909 1911 couple of 40s..Anyway i want to change my tone for 12.11 to 12.14 for these #s only. Can't do it on the ctx it only makes the bin bigger or smaller I want the same tone for my nickels as my penny's what to do.Dug only 6 beaver tails today i just need a tone that i can here that tells me i have a nickel tone without looking at the screen . Thankx
