Actually coppertop, we did make extensive use of Magnaflux for both large and small parts depending on what the inspection dictated. We used the X Ray machine for hidden stringers and beams in the aircraft's fuselage where we couldn't get dye penetrate to or use the scope. Especially for aircraft with multiple repairs once in an accident and placed back into service.

You are right about the way technology is improving. I don't doubt, that in the future, we'll have an I-phone App for doing a lot of what we do now. That would be nice. Cant see the Date, scan it with your phone and save it to your storage drive. Instant gratification...it's the American way! What a concept!

Regardless of now ane/or future tecnology the resurection of a date or mint mark on a coin would still make it an almost useless collector's item. Think of it. Would you buy a coin that someone said is a 1916D Mercury dime but you need a $50,000 machine to see that? Even a $10,000 one? Presently when serial numbers on guns are restored it is only to find out where it came from, who owned it, etc. Not even used on old firearms. Who in their right minds would try to restore a serial number on an old Mauser pre WW1 Machine pistol?
So someone at a coin store shows you a 1894S Liberty Head Dime and although you see the thing is worn flat, no details left at all, would you buy it? Now he shows you a statement that says under a $1,000,000 machine we now can see the details. So now would you buy it?
My point is regardless of what in the future someone can, might, could, probably do to restore a date on a coin, would you then buy it? If not, none of those processes means anything.
Of course someone on ebay might.
