Coin Chart...This where I need your help.

[Anonymous]

I put the coins down the best I could. But I need your help to verify the information as best you can and help date the era of circulation of the coins.
The information I have so far comes from Bob Brockett and transfered to the CoinStrike TID range. I am confident that the majority of the information is correct, but I would like some collaboration from you long time CS users.
The end result will be a reliable reference chart, out of which will come some date specific starts. Say something like a 1910 to present chart. a 1875 to 1910 chart, a 1750 to 1875 chart....you get the picture.
The goal is to date a site, then id the sought after coins that could be there.
Once its done, and as error free as we can get it, I send them all to John to put on the his CoinStike webpage.
Heres the chart:

& add some other coins that I have found too. My only slight concern is what I was getting at before....that often in the ground you will get slightly different numbers. I gave the examples of some indian heads being as low as +14 for me & almost all my large cents read +31 here. The thicker, pole capped one reads higher. I attribute this to the heavy mineralization we have here, & just assume when you combine mineralization with a "good" coin target, that the C$ averages it down a bit in my soil (even without averaging on). Maybe someone with more enginering savvy can verify this? (but I know others have said large cents in their ground match your chart). I guess my point is that in the few parts of the country with harsh soils, and on deep targets, you have to take that into account & expect some lesser readings. HH, Bill

So will machine settings. Thanks for wanting to help. I am not so much after a exact TID number, more of the primary range as I have them colored coded and lined on the chart.
Also know I have left off many coins, I didn't have information on Buffalos, for example. I think air tests for a number to id the range to include it will be sufficient. Then experience in the field will tell the user what to expect at a particular site as to shifting up or down.
I may have a magazine or book that can date the coins and maybe help fill in the coin gaps. Not for sure but I will be looking.
Its all just a guide anyway. All it takes is a nice angle on the coin to throw it into another range <img src="/metal/html/lol.gif" border=0 width=15 height=15 alt=":lol">
