<< <i>hmmm.......... maybe the slabs aren't as inert as i once thought >>
I doubt this is a slab outgassing issue. Steel cents are prone to that crap, I imagine ken was close if not on target with the pre-slab dip that wasn't neutralized.
I think Marty's weenie offer is interesting, but I would imagine PCGS will make the owner whole (if they haven't already). I haven't read through this entire thread so that could have already happened.

who (or is it whom) do you think did the dipping? just curious

<< <i>Hey Torinocobra71, What's the status of these 2 coins?? Did you send them back to PCGS or do you still have them? If you still have them, I sure would like to see some updated pics of these coins now to see what they are looking like now. Thanks,

Ask MadMarty. I traded two Cook Islands Dollars to him for them. He added them to his crud collection.

<< <i>These Coins were totally problem free before. These coins have TURNED IN THE SLAB. >>
then they were'nt problem free!
here's a good guess - these coins were dipped in a light acid solution FIRST, in order to clean off discoloration. then they got slabed. the problem is that the dip made the surfaces very reactive, which made them very susceptible to the chemicals that MUST leach out of the flexible rubber gasket inside the slab
dipping steel cents in very dilute acid is a old, old trick to really give them "pizzazz", but it makes them very unstable, too.

Yes they were problem free. they made it into a PCGS slab then turned WHILE IN THE PCGS SLAB, then became a problem coin!!!!!
After following this thread I thought I would add this coin to it. The stuff just keeps growing on this one. It is on the coin and I am sure PCGS would not have 67 it if it looked like it does now.
<< <i>Possible answers: a) You stored them in a fire-proof container.... humidity build up that leaked into the cases causing the corrosion. b) You stored them in a humid place, perhaps the closet in the bathroom? c) You ticked off the wrong grader and he put a little something on that submission and down graded the coins to a level they wouldnt be worth sending in for a grade review. d) None of the above.

This zinc oxide formation is from moisture, as David has said. Most likely all 1943 steel cents will decay in time. Most of the problem with these is rust. The sheet stock for these was plated, so the edge of the coin is bare steel. The planchets should have been punched out and then barrel plated before being coined. Any of these that are left in a humid enviroment will soon exibit this zinc oxide surface like yours. I have a thousand or so of these, and many of them are bad.
