Rare 1918D PR. 25 Phennig destroyed at CICF.

I'm a relatively new participant in this message Board. I agree with Andy Lustig's observtions of CICF. There were few great coins on the floor other than in the auctions. Stacks had some wonderful British pieces.
However, it is noteworth that Three Mark (Larry Gray) obtained a coin he had been searching for six years. This proof 1918 D 25 Phennig was a nice coin with just a bit of old cloudy laquer remining on the obverse. Six years of searching resulted in just one known examle in the Bundesbank Museum collection. Even the great Berlin Museum does not have an example.
Three mark decided to place it in acetone and then forgot it and went home early. A frantic call to me three days later and I found much of the laquered area seemed to progress to full blown PVC disease and eaten almost through the obverse.
I've never seen acetone do this to a silver coin. I'm wondering if there was a concentration of PVC in the acetone or on the coin and three days was just too much.
I thought this tragic experiece should be documented.

Acetone won't do that to lacquer. I wonder what was really on the coin?

I'm not familiar with a substance that would react to acetone in this way. Could it be that laquer was covering this damage and acetone simply revealed it by dissolving the laquer?
I would shoot it over to NCS. They might be able to do something about it.

Andy:
This picture was after a rinse in Koinsolv and revealed the lacquer. Thanks to Steve (GemWorldCoins) for his hospitality during CICF and the opportunity to room with MrEureka

This would be my take on the situation; the lacquer (or other substance) might have been covering a deadly disease of some kind.

What's your address and it's on the way to you
Larry, congratulations on finishing up your 25 Pfennig set. You have proven that persistence pays off.
Steve M., you are so bad. And to think I was going to send you that Potsdam Church 5 Mark proof you were looking for. Not after what you just pulled. :-)

My bad, I confused you with Steve H. on the practical joke. I'll send you that 5 Mark after all, if I ever find one!
