1 - Guessing some sort of
Die Deterioration on the 5.

2 - Not sure. Faded as all get out and mostly smooth like a baby's butt.


3 - Someone's science experiment. Chemical alteration? Probably watched that youtube video on how to make gold pennies. :)

Four more boxes to go through at some point this week, I'll try and post some other extreme examples I come across later in the week.
