Hi folks, Here is how it happened, I was using the Spectrum XLT. Ramped up Relic Mode. No Tone ID. Icons off. Head phones. I was hunting an open field near a 1740 grist mill. The soil color was black and damp from recent rain. While searching, I always keep a low threshold. At the target, the threshold jumped slightly back and forth over the target. The sound was solid though, not broken. The VDI was jumping from +30 to +60. The signal graph was only showing approximately 1/8" verticle. The XLT was trying its @$$ off to lock on. The depth was reading 8". I figured that it was something 8" but very small. This coin was down at least 15" give or take. After I removed about 8" of soil and no target, I checked the hole again and lost the signal. I knew that something had to be there. I kept digging and checking the dug dirt. I finally observed what I call the wrapped present. Many of you seasoned people will know what I mean by this, The egg shaped compressed ball of dirt that is holding the prize. Inside of that was the coin. I have found other large cents in this area that were more shallow but they had that traditional green patina. I think that this coin may have been deep enough to evade the depth of the chemicals that normally cause the green stuff. I think that every detector has it's VDI and depth reading limitations, but this find was found first by the threshold jump only. Hope this helps, thats how it went down.
