What would cause this?

So at an estate sale I bid and won a paint can full of indian head and wheat pennies. They were in a old outbuilding on the property sitting in the rafters. They opened them for the crowd and I was able to get them for $52.50. Counted them out and there where about 2500 pennies, but none newer than 1936. Most were common dates in f to vf, but some are in really good shape. Among them are eight 1909 VDB pennies. One of them had a strange silver spot on it near the back of Lincoln's neck. The picture is really of a quite brown penny but the lighting I took it under makes it look lighter, however it showed the spot best. Does not look like solder. Could it be from just being in contact with the paint can for so long? None of the other pennies showed any sign of this.

Well it looks toned so I would say a speck of something was on the coin and it caused the thin film of the toning to tone around it so to speak
looks like it was in a cardboard flip that had a small hole in it.
I have seen that before.
That could be from several problems... however, most likely some form of contamination prior to storing in the can.... Oxidation of the copper around it, and changes in the contamination result in what you see. Cheers, RickO
