I remember when I was on third or fourth grade, that a friend from Southern Mexico told me that the drug cartels would visit all new elected officials and ask the question “Silver or Lead?”, which of course meant, either accept the payola or we shoot you. Why would a nine year old know that I have no idea.
I had a free morning today so I went to my favorite park and began detecting at 7:00 am. At 7:30 I got my first high iffy signal. The depth on the AT Pro read ten plus and I am learning that iffy signals with that kind of depth reading and a bouncy target id could be old coins. So I made the hole and sure enough, somewhere around seven and a half inches I found a 1942 Mercury dime with no mint mark. This makes silver #22 for 2011.
I also found three large caliber bullets in different spots. I find bullets in this park all the time. These three are the largest so far.
Silver or Lead?
Once again, I have to say that I need to find a way to get past the eight inch limit. I know there are Barber dimes in this park. It was opened in 1901. But if I am finding coins from the late 40’s and later at seven to eight inches, the older stuff must be out of the reach of the Pro.
Deep silver
Thank you for looking.
The Dirt Is Good To Me 
22 silver is prettydarn great, congrats! Not knowing the AT Pro at all I couldn’t make a guess on the older stuff being out of its reach. What is your max depth on a coin with the AT Pro so far?
I know the Minelab’s absolutely sing LOUD when silver is around so if you have access to one of those or a friend with one you may be able to guage if there is older deeper stuff around.
Anyways take care and well done on the blog! Love the frequent posting.

Thanks! My deepest coin was a wheat cent at a little over 8 inches deep. Yesterday, I found a Roosevelt dime at just about 8 inches. I think I may have hit the limit on the depth for dimes anyway. Someone told me yesterday that they have found dimes at 9 inches. Maybe their soil is better.
Sounds to me like you are probably correct. There are so many variables at work here; soil condition(as you already pointed out), coin position, individual machine charachteristics, etc. etc.

I’d kill for depth like that around here HAHA. Very nice.
