old coins give off low iron readings?

Heard that some old coins give off low iron readings. just wondering if I should try diggen up everything. Or maybe depends on the depth
 
I don't believe any copper or silver based coins will appear in that band. Gold coins may as well as coins made from iron alloys.

When coin hunting, I discriminate-out all iron.

Have found corroded wheats and Indian heads at depth as well as older silver dimes at depth that may ring in the iron range. If I stay on the signal it may bounce up to nickel or higher.....only then do I dig it. I've gotten a lot of the aforementioned this way that I would have passed over in past years.
 
Wow, I wonder if it has to do with the coin attracting minerals from the surrounding soil or something like that, a galvanic corrosion phenomena or something akin to that.

Just asking but could it be that the ID circuitry on the detector cannot distinguish the difference between a coin and something else at a "max depth" again, just asking? I have found a number of washers that "fool" my ID into thinking they are coins. Could this work in reverse? Maybe between the oxidation and ground minerals my machine thinks it could be something else. From what I understand about the ID system on most detectors is they look at " coin sized" objects to determine what to indicate on the screen. I guess the "dig everything' rule applies. However I could be way off the beam on this one, as is normal for me. Again, just thinking out loud, so to speak.

Use a five year old Discovery 2000. Very fragile machine which is held together with super glue and solder, but still works well. Accurate coin shooter to about 6". Beyond that signals tend to bounce around. Today for instance I dug a bouncy signal (iron/nickel) at 7" and it turned out to be an 1898 IH penny in good condition w/ green patine all over. Once out of the ground it rang up like a zinc penny (clad) as have all IH pennies I've found. I also find that rusted iron objects ring up as anything but.
