Carbon spots

[Guest]

Hey Fellas,
Earlier this week you said that Those where carbon spots on my 83 d coin I showed and there was not much I could do about it. Well I know I would not have saved that tube of 80's rpms if they looked liked that. So I am opening up stuff that I put away many years ago just to see what they look like. Some tubes just look like POOH while others are fine. I know I would not have saved some of this stuff.
So question: > What causes the carbon spots and do the continue to get worse.

> Some of the tubes that I wrote "Gems" or "keep" on have some green **** on a few of the coins in the tubes. Is that growing and will it spread and what to do about it.

More than one question but I hope someone can cover the whole area of this problem. Sure would be a big help.

Oh and one more thing I did smoke alot back then even in my coin room. I KNOW TAKE IT EASY. Dont anymore
I am sure that is part of the problem.
Thanks jim

Jim: There are some soft square tubes that have PVC in them and turn BU coins into ugly step sisters in time. I just use the hard tubes or the round clear plastic ones for BU coins now.

I used to label my coins with a brother label maker and would wrap the corners on the inside. I'm now finding this also tones the upper part of the coin. So I make sure to cut them to fit only on the outside of the 2X2's.

Ok Coop, The green mold looking crap. I guess thats from a minute particle of something landing on coin. I am guessing. Does that stuff spread in the tube to other coins?
I remember the label maker. I still have the 1962 Doubled die you sent went I was just learning about them. You sent it so I coiuld tell a dd and quit showing you machine doubling and thinking I hit a gold mine. lol

The Soft tubes seem to usually affect the top & bottom faces of the coins and the edges. In time they would probably affect all of the coins.

Many tubes will turn your coins. Staples will turn your coins if near them. Many different albums will turn your coins. Many cheaper flips will turn your coins. Storing coins in the heat or cold will turn them.

Sad answer is, once the coins have turned there's no good way to bring them back. Some might be reasonably more successful than others, but for the better part the gunk or the treatment to remove it will ALWAYS be detectable.

Best thing - store the coins ONLY in archival safe flips, not staple 2x2s. If you get tubes, get the CLEAR, hard plastic tubes with screw caps, and DO NOT use tape on the tube. Store the coins in a cool, dry, dark place like a closet or a cabinet indoors.

I've seen the same thing from the square tubes, the end coins get a haze quickly.

I think hard plastic tubes are about the best thing for storage, I think they work better than flips for long term. The thing is you need a full tube of bu coins for it work.

On some years like 83 they had bad plating and bad rinse. Many OBWs have coins covered with black spots and there's no way to fix them.

The green spots are verdigris. You need to isolate any coins with verdigris on them or it will spread from coin to coin.

It sounds like they were improperly stored. Always use multiple layers of protection. I keep all my tubes in ziplock bags and then I put those inside Tupperware containers.

Mo layers = mo betta

I have to agree that only hard plastic tubes hold MS coins safely. Do not mix coins from sources you do not trust. It is better to spend the money on the tubes to keep them separated. Once that green stuff begins it is hard to remove.
