I ended up mixing it with water to get there. Sufficient humidity is the problem.
This lamp is the lumens equivalent of a 40w bulb; I doubt it's too bright for anything coin-related. Looks like a good research tool, but the head...
I fear the coin has suffered a harsh cleaning. This is evident by the gunk caught up in some small, tight areas of the coin, while the rest of it...
It's how you learn to grade from images, just like how you learn to grade in-hand. You look at a hozillion of 'em. :)

That'll be budget-dependent. I use the same rig built for coin imaging, a Canon dSLR/bellows/duplicating lens setup controlled from the computer...
The regular (and measurable) thickness of the stroke does lend itself towards the die gouge theory as opposed to an expanded crack, but the...
Everything's a shiny object to me. O Look! A Shiny Object! :)
Always a pleasure. :P
