improper annealed planchet.
There's one easy way I could tell
it's genuine - can anyone guess
it's not bleeding thru any clad layer.
I'll post the answer in about
5 minutes, if that's OK
It's a result of a loss of protective atmosphere or being stuck in the annealing furnace for a prolonged period of time, or both.
Yes Rick but how could he tell
Blackening on/or from the planchet and good images ..
genuine mis-annealed planchet because:
Every single 'mis-annealed' coin that someone
has shown me at a coin show, or in an email, that
turns out to be environmentally damaged or played with,
has a darker duller surface than it should have, AND
every single non-error has the same dark color
on the reeded EDGE of the coin.
See the edge photo (#3) - it looks like a normal
BU Quarter - the copper core shows a nice normal
red color - that's because although the planchet
itself (on a genuine mis-annealed planchet)
would have the dark color on the smooth edge,
once it's struck in the collar, and ejected, that
dark color is removed from the reeding due to
the ejection of the now-coin from the collar.
(I could also tell it's real from the surfaces themselves, -
although mis-annealing leaves a range of 'darknesss',
seeing the reeding as a normal red copper color is one
of the keys to know it hasn't been played with)
Hope this helps - it's a good authentication point
to check, if you're not sure of a 'darker' color coin
is truly mis-annealed/improperly annealed, or has
been played with after the coin was in circulation.
Yes it helps.. Thanks for the the formation!
planchets are uniform as to the
darker color on both sides, there
are some that show a normal
surface on parts of the coin, due to
how it was laying in the annealing
drum when it dried.
That's a good thing to look for, but
there are exceptions.

have the darker color ON the
Closing the office now, will see
you all tomorrow morning.
Could you please tell me your opinion on this coin I posted? The reeded edge looks like Rick's coin.
Based on the edge of the coin in your link above,
it looks genuine.
