2) take a Dog to a rock concert.... if you want to detect a pin drop! -- pertains to the concept that you should use a detector that cannot hear the noise, it only hears the signal you want to find.
3) google Seebeck effect -- pertains to the concept that the Seebeck effect, or Peltier effect of generating electricity from the junction of two dissimilar metals at different temperatures will allow an IR LED to detect a buried coin.
4) to be continued....more to come -- pertains to more examples like those above to be seen in future episodes of how an IR LED responds to the thermal gradient of a buried coin.
I must congratulate you for persevering through the challenges that tend to illustrate how the thermal gradient of a coin cannot be detected when buried some distance below a normal soil surface.

Thank-you, J_P, I have no illusions of the difficulty of the task.
I just prefer to approach this problem from the position of:
"If the reported phenomenon is true, Why is it so?"
rather than:
" I don't think this can work, here's why!"
and especially:
" I don't think,.....this can't work,.... it's all BS....show me the treasure!!
Dialectical discussion is fundamental to development of deeper understanding of any issue. I am enjoying the process.
