Updated
The coin was earlier shown by member lkeigwin as an example of the effects of MS70 on copper. He sent the coin to me and agreed to let me use it as a demonstration piece.
Here are his images:
Before:
After:
So I got the coin and here was my image:
My contention here is to show that the purple toning is not a factor of the MS70, but it showed up because of the way the coin was stored for somewhere around 50 years. It was likely retrieved from circulation after a year in circulation, and put into an envelope. Over the years in that envelope it acquired a deeper brown toning which is a combination of the purple tone and debris and oils that accumulated on the coin. When the oils on the surface were removed, the purple tone showed itself.
Now, the proper thing to do to a coin made naked, is to reapply the oil that was removed. Using Blue Ribbon Coin Preserver, I took a tiny drop and applied it to the coin, first just one half, then the whole coin.
Half coin with oil:
Full coin with oil:
I could go ahead and remove the oil and the purple will come back. The purple will only show up on coins that have been stored for many years in some type of envelope, just any coin from circulation will not show the color, just a an unnatural slate color, which will revert to brown with Blue Ribbon.
I would recommend that any collectors who get a purple-toned coin that looks like it was treated should apply a drop of oil to it to revert the color to chocolate brown. That is the "normal" look.

to much scattered nicks and stuff on the obverse for my likes
there must be a story behind this if you're posting this...just not the type of coin here i'd think you'd have interest in
something gives here eagle-eyed one
change find?
was color not accepted?
could of had a spot removed in the "C" of cent too that caused a bodybag?
hopefully not fresh out of the shanghai express press
Rims look MS, but there looks to be some friction rub on the obverse.
Coin has an old oiled look.
I like old oiled looks

+1 - 58, has the look of being lacquered.

Experience the World through Numismatics...it's more than you can imagine.
Though 62 was my first impression.
Edited to add...
Nice coin... Though I echo VegasTeddy her in wondering

The strike and surface texture remind me of an MPL, except for the lack of hair detail.
Rub on cheek, jaw, obverse rims and central right obverse field.
The reverse could pass for unc.

I would grade it AU58BN
<< <i>Anyone else see the irony in Rick Snow asking for our opinion on copper? Anyway...I don't want to disappoint so I'll say 58, just doesn't look MS to me. >>
yeah my comment parallels yours
ricks up to something with this one
it must of bagged or is counterfeit or something
maybe he'll update with a picture of copper foil peeled back displaying a chocolate center with "wonka" stamped on it...

So this isn't a GTG it's a GWYTIWG (Guess What You Think It Would Grade).
Great thread.
isn't the pcgs "coin sniffer" is set up to detect these products and reject coins accordingly
if such is the case
pcgs would give this a "no grade" genuine only assessment
would they catch such 100% of the time...probably not
but i believe they look for such

A GTG with the image above image prior to oiling with "Care" would have been fun!
It's amazing how many cents with this post blue ribbon look make it into plastic.
Every collector should buy some of the chemicals available to experiment on common copper/silver just to own a enhanced (doctored) set for learning & reference.

I doubt the sniffer would reject Blue Ribbon or the pops on early copper would be dramatically lower. >>
Don't they only 'sniff' upon request? My feeling is that if checked for it would probably detect it - unless it were applied a very long time ago.
surely a submitter of doctored coins isn't going to request sniffer service to be included...
and yes i consider this coin doctoring...that's the crowd i'm in...no need to debate or try to "doctor my opinion"
while others may not think such...peace be with them i say
