OK Lets Try 1932 D And See What We Get

The Wheat heads left side is tone so I did not think I should have included it but as it detracts from eye appeal then I guess it should have been.
Thanks for the help, these three coins have given me a much better understanding of Lincoln grading. Time to put them back in their album and stare for a while at the two holes that will probably never be filled.

Carbon spots will grow as time goes by unless the coin is sealed in an Intercept Sheild or similar.
Enviromental Damage is usually some form of corrosion caused by the enviroment the coin was stored in I think in this case Lincoln is surrounded by red hailstones. I am sure some one will corret me if I am wrong on this.
I do not collect copper as a rule the only exception being 2 Cent coins and in that case I am not realy interested in the colour just varieties such as die cracks. So my grading skills and knowlage are well below par.

Nohope is correct, carbon spots will grow ,unless arrested by storage in an inert environment, the red surrounding lincoln is a form of corrosion , often caused by temp changes and humidity but not limited to those environmental conditions,I see them quite often on coins that have been in storage in the older penny books.and some that have been stored in the original paper penny rolls.
I call it copper rust ,I have never heard the exact scientific name for it that I can recall.

This type of red seems to be limited to the BU cents I have never seen it on circulated coins.

Just another reason why I like AU Lincolns, especially for my book collections.
