I apologize for leading the thread off subject, and for stimulating Ruben :) [/posting off subject]
I very strongly suspect that Ruben's photo is PhotoShop textile toning. :)
[/COLOR][/LEFT] Actually, it is the confocal laser microscope that is out of my reach for "hobby projects". The transformations are basically...
Which makes me wonder if their neat laser fingerprinting machine has the software to intensify certain areas such as date, and run a statistical...
Some firms do separate them by dates and mint marks. A mixture of all dates and mm will have a predominance of 1950, followed in sequence down to...
Since these are zinc core with a thin copper layer joined top and bottom, these are almost always a bubble between the copper layer and the zinc,...
That's neat. Once bought a bag of Susan B's, they just turned dull. Now if you accidentally put some Morgans in it, they will be NT, but if you...

Ruben watch about 2:13 into this PCGS video with the President of PCGS. They do first eyeball the coin, and then the "glass" comes out. Remind me...

[/COLOR] I didn't have a Hasselblad on my Electron Microscope, as film backs were considered not flat enough at that magnification, so we used...
It is subjective where toning/tarnish/corrosion is concerned. Generally toning/tarnish is the same. If you like it, it is toned, if not, it is...
Actually I feel that coin is attractive, but that is me. If the reverse was equally toned, I would really love it. Could you post a photo of the...
If you look in the coin magazines and on ebay, PCGS and NGC participate in this first struck-first day-place of ceremony -MS-70-modern mint stuff...
Welcome! Since it was graded by PCGS, it is market acceptable. The colors seem natural for teh toning. Yes, sometimes they do tone green (See...
A factor not yet considered is one which affects Variety collectors. PCGS only has a set number of varieties ( say Lincoln cents) they will grade...
We must remember that not too long ago, most toners never reached a selling position, as they were out of favor and summarily dipped to...
