What happened to my taler????

Silvereagle82

I bought this Austria Salzburg taler last September at the Superior Galleries Pre-Long Beach auction. I opening the sealed flip (Seems like Mylar to me) it was it carefully and with cotton gloves took a couple of photos, put it back into the flip (unsealed at this point) and put it in a hard plastic slab box (It has a few other coins in it also) and then put it in my safe deposit box at my bank ( I keep a dessicant bag in it)

Yesterday I went to retrieve a few coins I submitting to NGC, this taler being one of them, and this is what I found

BEFORE:



NOW:


The obverse hasn't changed !!!!

Any suggestions of what I should do ... or if I should do anything !!! I wondering if a quick dip in acetone will clear this toning (if that is what it is) or don't bother and get it slabbed a quickly a possible in an attempt to keep the spot on the coin from darking any more.
What ever I do this is a great looking/condition coin and I don't want to get this coin BB at NGC!!


Thanks in advance for any feedback!!!!!!!

acetone won't help...

another reason I don't trust banks...

Wow, that's crazy! I wonder if your bank's vault has any special environmental conditions, such as pumping in extra humidity to keep paper documents "fresher" longer. You might give them a call and ask. Sorry to see that happen.

Acetone *might* help, in any case it wouldn't hurt. If this is in the metal itself now - you're screwed. Your choices then would include leaving it be, dipping, or sending to NCS.

Whoa...

I can't figure what that is, although I'd think it needs to be removed.

Possible transfer contamination from the safety box metal, or else someone handled it prior to the auction. It's a beauty though. Maybe NGC can help - they have that NCS department, although I don't know much about it.

Looks like someone performed a bad Jewelustre dip on it, and didn't neutralise the acid, or properly rinse afterwards.

NCS can take care of it "properly", and forward to NGC to grade....most likely anyway. Good luck.

it's odd that after seeing the 2nd pic, in the "clean" picture you can actually see a disturbance in the exact spot that became problem'd,
since it wasn't slabbed, maybe someone did something untoward before the auct ? bizzare.

Was this coin white when you bought it?

If you remove the shmutz there is no guarentee that it won't come back again. This happens from time to time with NCSed (or otherwise curated) coins.

<< <i>Was this coin white when you bought it? >>



Yes it was..... but in the auction photo it appeared to be much darker than in hand.
Obviously the coin has been cleaned (Via a dip) but in hand I can see no signs of any harsh cleaning or wizzing ( w/16x loupe) and the coin does have some lustre. The field marks are normal wear and planchet grain.

In hand it is a very nice hi-grade taler.

In a email to NCS with photos they seem to think it is caused by a fingerprint (or I guess moreso by what was on the finger) and they may be able to help and barring no improper cleaning or evironmental damage get it NGC graded.

JamminJ, I can only hope that the shmutz doesn't come back after getting it cleaned and slabbed

So off to NCS/NGC Hieronymous goes !!!!


PS
Thanks to all for the feedback!!

Before sending it off, I would an acetone soak (it couldn't hurt).
