Great discussion - thanks for posting. It also gives some insight into 'chemicals vs water', for those who aren't aware of the different effects that the two have on paper.

I once owned an E95 Cobb that was significantly altered by adding at least glue, some coloring and almost certainly chemicals. It was then sent raw to at least two different TPA's. Since then I've reached the conclusion that it was done as a test, since it didn't significantly change the value of the card, and since the same owner got it slabbed by one TPA and then sent it to another (perhaps even a third?)

The point it - at least three different substances were added that were foreign to the original card, and at least two TPA's didn't notice, and assigned numerical grades.
