    What I was thinking, Greg.

    You know when a judge or cop gets caught with evidence tampering, or something else illegal...

    It puts into question every case they have ever been a part of.

    When PCGS slabbed this, that's what it makes me think of.

    I don't buy the statement that only electrical field was used with no heat or chemicals. Electroplating involves chemicals or metallic substances ( which I would include as chemicals), and any induction heating would still be "heating" , even though it was generated internally. I think he is trying to introduce an acceptable ATing between "Real AT" and non-AT. I have generated such coloration in high freq RF equipment, but they got hotter than the Mayan weather report for today :) as it occurred.

    Has anyone got a copy of Sunnywoods color progression chart to add as a learning aid of how colors should progress on naturally toned silver coins?

    Yes that is what I mean ounce you get the progression set in your mind it normally just takes a glance to say yea or nay.

    i have been watching this beautiful coin on eBay since you had it listed for $2,000... I certainly hope you sell her before it gets any lower than you have it for currently at $640 :)

    Well, I won that coin - evidently nobody else was dumb enough to bid on it. But I really am curious as to what the electroplating looks like in hand, and at $7 over spot, I don't think it's too expensive a learning lesson.

    I think I'll put it on a big gaudy chain and wear it to coin shows. HAHAHAHAHAHAHAHAHA!

    Well, I got this coin today, and actually I'm glad I did. There isn't even a close comparison to the NT coins I own. The bands are too uniform in color, without the splotchiness of NT, and the color seems to sit on top of the coin, rather than be part of the metal. Also, whatever electroplating process he uses strips off a lot of the mint luster, leaving the coin rather dark and dull, despite the rainbows. Very interesting - I don't think I'll have a problem spotting this type of AT in the future...

    after looking at your pictures of the coin that is the poster child for AT coins. its definitely a good tool to use to spot AT from NT. i have quite a few walkers that have similar colors but the toning is in a much different pattern. they have even changed their color slightly over the years that i have had them

    It doesn't exhibit the erratic blending of colors that my NT pieces have. I'm the sort of novice that could have easily been duped by such a piece in an LCS.

    Me: Oooh, ahhh, my preciousssssss...

    Dealer: It only costs a Franklin. You don't see these every day! **winks at Igor in the back room** They're selling for 650 on eBay!

    Me: Here's my card!!! Quick, before somebody else walks in the store!

    John, Is the background color ( looks like album page) actually those colors?? Looks like 2 shades of gray on my monitor.

    The reason I ask, is that if it is "creme" or white , the white balance should be set before shooting, especially necessary to evaluate toning, as is often mentioned here about ebay listings. If ypu don't have a "white balance" correction for your camera, you might try under different light bulbs to get accurate color rendition.

    I agree Jim,

    You can also compensate for the white balance issue with an "auto-color" adjustment in image software, like so...

    And then give it the "Tru-View" juice!

    Hey, thanks for the tips guys. Greg - your edits are perhaps a better representation of the AT colors, but the coin itself is curiously dark overall - it looks more like cu-ni clad than coin silver.
