Looks like heat damage. Zinc has a lower melting point than copper so it tends to rise to the surface.
I did manage a find some nice toners from the 1970's in my gem quest. Sometimes an OBW gives back some encouragement! [ATTACH] [ATTACH] [ATTACH]...
TOUGH coin, for some reason these always look like they went through a meat grinder straight from the mint. I opened many OBW rolls, the 70's are...
The sure liked to polish those dies! Some nice orange toning on this one. [ATTACH] [ATTACH] [ATTACH] [ATTACH]

Inherited this from my Grandfather who started collecting in the 1940's. Plucked it out his completed Whitman Lincoln folder. I remember him...
You might be on to something, that was my gut reaction to the pictures. HOWEVER, these are 2 pretty crappy pictures (IMO) and they are...
Disclaimer: I am NOT an MPL expert! I have eaten crow a couple of times in 20 years. lol However, I am the eternal pessimist on MPLs because they...
I hear it works well on Lincolns too! I wonder why? :D
Wow, that's COOL!
