I was able to do some airtesting this weekend after the snows came & kept me at bay.....
Remember these are airtests, and mineralized soil can change things. But, I was encouraged to see that, like I thought, TABS (all the ones I have) were way below Indian heads & Wheat pennies....
TABS
4 diff sq. tabs (newer style) 36, 37, 38, 40
3 diff. round tabs- 33, 39, 42
Round w. folded tail= 34-35
round w. tail= 42
Buffalo/V-nickels- 29-30
1900 Indian head= 58
1906 Indian head= 56
1872 Indian head= 57
1865 Indian head= 46
1863 Indian head(fat)/Flying Eagle= 45
Wheat Pennies
1952= 71
1948= 69
1939= 64
1919= 68
1920-27= 65
1910= 59
Silver coins
Washington quarter= 84
Mercury Dimes= 73-74
Roosevelt Dimes= 75
