my first use of acetone: success !!
ok, this is darkside, but I figured the pics would be interesting. I found this 2004 canadian quarter design neat, so I started looking for them 'in the wild'. I wound up purchasing (online) an old original oh canada! package which contained the coin in original mint packaging (plus a t-shirt!) anyway.. when I took the quarter out of the cello package, it had this gunk on it:

(forgive the flash, I was trying to bring out the splotches)...
I figured this would be a good acetone test ? I picked up some the other day, off the shelf in lowes. I q-tip swabbed this out in the backyard.. results ? good! I guess that means this was plastic poisioning ??? note: In retrospect looking at the second shot, I might have just moved some of the gunk around rather than removing it totally, I guess I should go for full immersion ? I was leery of really rubbing the coin with the soaked q-tip.

I still have NO IDEA what the striations are on the coin. Id be interested to know what they are if someone knows.
pardon the blur, this is what we look like no under the flash, I neat darkside modern piece of fluff (IMHO), it looks VERY NICE in-hand now!!!

(obligatory) WARNING: ACETONE IS AN EXTREMELY NASTY HORRIBLE SUBSTANCE. (incredibly flammable and noxious to work with). Please Please handle this crap with care, I dont want to see anyone get hurt, burst into flames or otherwise torch themselves with it by accident.
That is all, move along.

I usually just blush.

Interesting. I've never seen it. I buy a lot of Canadian proof coinage.
