Went out and played with the EX2 and 12.5 coil recently. Here's some of the deep "iffy" stuff (of course I wont show you the ton of debris I also dug). The two IH's are the in the best condition if ever seen dug. I only washed them with water and rubbed with my fingers (I know, dont do that). Interesting note about the two wheat pennies. I 1915S and the one on the left? 1914D!!!!! First one in over 17 years! Had to use a magnafiying glass to get the date as it is in such bad shape though.
