well that is a huge bummer on those spots - question though - how often did you take them out and replace or dry them out?

https://www.ngccoin.com/news/articl...ickel-coins/Well, the before and after photos on this NGC article suggest that conservation can rescue the coin. Apparently the spots can be caused by exhaling moisture, paper dust specks, and other micro-contaminants.

Dearborn - never, first time I've looked at them since they were capsuled 3 or so years ago. You saying that coins should be removed every so often and aired out?
This weekend will involve breaking open every capsule I have for an quick Acetone dunk (except the proofs)

DOCC, if the culprit is exhaled moisture or airborne dust particles, won't opening all the coins pose a significant risk?

Ya jumping the gun with that statement. Now I just fear poking thru some of my collection that has not been viewed in quite some time.
Got the gunk out, each big spot on each coin ate metal...totally sucks.
Not high value coins but they "were" nice specimens. 65 def cleaned in its past, uncertain on 64 toning as 2-Cents can be all over the board.

Oh gotcha - I replace them if they color but will start on a yearly dry out phase. I bought some new desiccants that you can put in the oven to rejuvenate. Went thru 100 or so other coins and no spots yet

I had a 2¢ collection over many years and never had a single coin spot like that. That would freak me out, too. I always have dessicant in my storage areas and try to swap out on a somewhat regular basis. The only 2¢ I've owned with a carbon spot is in a.PCGS PF64RB and it's stable. As far as removing, I doubt that's possible short of damaging the coin. What I would do is dump those coins, repurchase, and make sure they're carefully maintained. Really scrutinize any new ones.you buy to make sure there's no.hints of anything like spittle already act on the coin.

I use Eva-Dry. Here's a hotlink to it on Amazon. It's color coded, so when it turns green, you just plug it in to dry it out, and you're good for a couple of months or so. https://www.amazon.com/Improved-Eva.../B000H0XFCS/I also use Lighthouse Intercept Shield boxes, from Brooklyn Gallery. Keep in mind those last for about ten years, and should then be replaced. Steve Edited by Winesteven

Will give the Eva-Dry a try for the drawers these are kept in - that way I'll have an indicator at a higher level. Went thru entire collection and found about 1/2 dozen other carbon spots. Each went under scope and each was a piece of lint/fiber - that is also what was on each two piece. I'm guessing it was from the bulk capsule purchase box. Needless to say, bought a 6-pack of compressed air cans for all future capsuling endeavors.
Removal on these pieces going better than expected, I'll update with pics when complete.

thx for the heads up, so just like a basting thingy for cooking? Big bulb so you can get a good shot of air?

Precise work required but can be removed. This is after treatment and 10-days on a windowsill. Evidence remains as NGC calls out in the article Brandmeister linked - inconsistent coloration. Will leave on sill for a few more weeks to see what may transpire.  |
