<p>[QUOTE="Electron John, post: 2613142, member: 84417"]The coin must be out of its holder to image it and to do elemental composition work (Energy Dispersive X-ray Spectroscopy, aka EDS). Other than that it is a non-destructive analysis. But the electron beam has to come in contact with the coin to work, otherwise it just detects what the holder is made out of.</p><p><br /></p><p>What would work for analyzing a coin in a holder is a handheld X-ray fluorescent (XRF) analyzer. I have a friend that uses one for field geology work. You don't get any images but you get accurate compositions from magnesium up to Uranium in seconds.
