Elevation Chromatics (a term developed by a toned coin expert named Brandon Kelley) refers to how the color progression on some toned coins lay on a coin's surface over different "elevations" of the design. The lower "elevation" of the surface will be toned in one color while the higher "elevation" will be toned in another color. This is elevation chromatics.

The Morgan Silver Dollar shown below is one of the best examples of "elevation chromatics" I've ever seen ... an 1882-O Morgan (PCGS MS63 OGH) that I bought a few months ago. Take special note of the hot pink coloration, which appears to "flow like a liquid" covering the lower recesses of the coin design; and the surrounding "higher elevations" of the design are toned in green.

 

Picked this up on eBay the other day. Adding it to my 1943-S collection. All I need now is a nice '43-S Merc

.

 

The 1977-S Ike is Copper Nickel.

 

Thanks, WingedLiberty! Learned something new today!

 

I thought so i was even going to go out on a limb and say it, the yellow color around the rim is a dead giveaway. Beautiful coin....

 

Very nice! I cannot wait to post my new acquisition tomorrow.

 

part of the mint sets i picked up this morning. i didnt realize how blurry the jefferson was until i had it blown up.. shows the toning really well however

 

1983 D and P Souviner Sets

I'm wondering if the P set was picked from the bottom of a bag - the quarter seems a bit banged up. I'm still happy I found the sets!

 

Looks like it was rolling around in circulation for a while. The 83's are a tough date though, individual mint state examples go for $15-20 unslabbed.

 

If it's such a "slow process", why does it appear on your 35 year old Eisenhower? I'm not being polemical, I'm truly curious. Also, do you have any scientific evidence to back up many of your statements? For example, why is this pattern "practically impossible to reproduce artificially"? It would be nice to have Tom B's input on this process... While you give lots of opinions about its "rarity" and its "naturalness", I'd like to have some of the science as to the actual process -- beyond the explanation that it occurs "under very unique and special conditions".

Cool coin Winged. I don't get too excited by Ike's, but that one is not the regular run-of-the-mill Ike. :thumb:

 

I just learned about elevation chromatics a few weeks ago after posting a morgan dollar on the PCGS Forum. An advanced collector provided me with the term and the link. I googled that term and could only find Brandon's reference, so it appears he coined the term. Happy reading!

My statement that this is difficult to cook was excerpted from his write-up -- but this is really all pretty new to me so please excuse any mis-statements on my part. Like most things there are probably always exceptions to the rule, but I just havent stumbled on them yet.

If you uncover any additional information, please post as I would love to learn more about this, and there is just not that much info about it on the web (that I could find at least).

 

a few more eisenhower images

 

Thanks for your input kookoox10! Still,it looks better than the average 1983 found in today's change! And the 1983 D quarter looks great.

 

"elevation chromatics" is better than the average made up term.

 

This is 2 different shots of the same coin. It's a toned Morgan I picked up at a show a couple weeks ago. It's got some pretty decent toning on it, I just failed miserably at capturing it--especially on the obverse.

 

Here's another Morgan, I just picked this one up today. While it is pretty scuffed up, the obverse is semi-PL which is what made me buy it, plus the fact that the LCS I got it at didn't have any Franklins that caught my eye.

 

A couple of recent eBay pickups.
