Rick Kay's research and Milk spots

CoinHusker

After reading the thread by Rick and his fascinating research,

<< <i>As many of you know, I am researching all facets of the 1854 & 1855 LFEs. One importantt portion of this research is testing for metallic content via Scanning Electron Microscope Energy Dispersive X-Ray (SEM-EDX). This is non-invasive testing in which s-rays are shot at the coin, and the usrface layer of the coin is "analyzed."
>>

, the thought hit me. I wonder if this technology could discover what causes and point to a solution of the "Milk Spot" problems on silver american eagles?

It's been discussed time and again about how milk spots are not "on" the surface of the coin but apparently "in" the surface of it instead. That's why Rick's statement, "the usrface layer of the coin is 'analyzed'" intrigued me concerning SAE's.

Similar techniques are currently being pursued.

Well, so much for MY bright idea.

The electron microscope, and the diffraction spectrum is produces only works on metals. Unless the milk spots are caused by some alloy difference, it won't detect anything.
