Everything But Silver

What was the dTID on the Indian Head?  My 95% copper (small) USA cent finds go all the way from 19 to 26 (ML Eqx with 11" coil, mostly hunting in Park 1, RC = 4, F2 = 0).  I think corrosion from ground minerals is a key factor for copper alloys, but I still need to do some tests with the hundreds of Wheat cents I have (specifically those not found with a detector) to see if there are other hints/clues.

Since I dig every small sized target above the Equinox dTID of 21 (and many in the 19-21 range) that doesn't have strong ferrous dTID content, I don't go out of my way to nail the dTID before I recover.  It does seem that silver dimes center a bit above where 95% copper cents and clad dimes do.

The IHP was a 19/20. Solid 19 in an air test.

Here I've retrieved Zincolns that were 18-20, the wheats and pre-82 memorials are more 22-25. Dimes will throw 23-26, I dug 7 clad dimes. Unfortunately aluminum bottle caps are 20-23 so they sorta look like pennies, dug quite a few of them. ?

I am guilty of "strip mining" this yard and then will use my 11". I should get a few more inches deep but I find many coins masked by junk. Got an interesting post forthcoming. Hopefully I'll find one silver, but it may have been cherry picked. I just can't believe that the "picker" also didn't get some of the coins I did! Literally one every 5 minutes or so.

I dig about half dozen of those in a 3-4 hour session.  Shallow ones are loud (but so are shallow pennies...) and I get a surprising number of deep aluminum screw caps.  I chalk those up to my nemesis -- landscaping backfill.  But a couple Al screwcaps per hour really isn't much of an annoyance, for me anyway.  Zincolns on the other hand....

Sounds like it was cherry picked. Pretty much any silver I find here is in the toughest spots to detect for coins at least. Areas that the older machines struggled with. Now even older coppers are hard to find so I been hunting more jewelry in the aluminum crap. Not sure what is worse, hunting in aluminum or iron. Have a lot of new places to hit later this season when undergrowth is down.

I considered a land pi a few times, even an ATX but know that other than punching through the ground for depth the trash levels are just too high. I do well with all metal hunting to sniff out targets of the right size and depth then will use discrimation mode if I need to. Having a good threshold you can hear a lot of stuff you normally may not hear with discrimination on all the time.

I always run in all metal! Lots of Beepy Boopy. I am in Park 1 and 5 tones, but experimented with 50 today. Considered threshold as well.

I don't think depth is a problem here, more masking/inexperience. Time will tell if I am right. ?

By the age of the clad it seems like someone back in the day hit that area. More obvious targets like quarters are scarce. Thinking masking is less of an issue.
