Paper enveloppes: good or bad for silver coin storage?

I guess it depends on the kind of paper envelop and what you want to have happen.

They can produce some wonderful toners. But they are slightly abrasive. So put em away and don't disturb for a few years.

Most paper envelpoes will tone your coins overtime.

I use them all the time for circulated coins. I wouldn't want a mint state coin sliding around in one though.

I store my 1oz Silver rounds in the 2x2 coin envelopes... Hopefully in a couple of years I'll find sme nice toning If not, no big deal...

i would imagine they cause hairlines on UNC coins>?

They can cause wear on high grade coins, but you are safe if you use a flannel insert inside the envelope.

I've had 3 coins on the dash of my car here in Florida for 2.5 years. One is in a Kraft paper coin envelope. One is in a white #10 envelope. The last is in a Taco Bell napkin.
The Kraft envelope coin show no evidence of toning whatsoever. Same with the white #10. The Taco bell napkin, which has only been there for 6 months is showing some nice toning.

So, you can't say that "all" envelopes will cause toning. Clearly they do not. If no toning in 2.5 years, on a hot dashboard, no toning will probably ever occur. Probably safe to store all my silver coins in those envelopes. For those who say that they believe toning will occur in ANY envelope, you're going to have to re-think that. It doesn't always happen. I won't go so far as to say it will never happen, but I don't see it in my little experiment.

You used to be able to buy a soft cotton pouch that would fit inside a 2"X2" paper envelope. These were popular with large cent collectors. Not sure if they are still being manufactured.

Sometimes coins will have an invisible film on them that prevents toning. If you give those coins an acetone bath, then return them to their former environment, you may be surprised at what happens.

PM Numisma, and he will remember the copper dealer who sells them.

I bought some paper envelopes with a felt (or cotton?) insert called Gemvelopes, about 20 years ago, and I have kept my Unc and Proof SBAs and Ikes in them ever since.

The results? Some of the coins started to tone, but not dramatically. One of the Proof Anthonys is turning a golden color, one of them is developing a light, but attractive tone over the entire surface.

One of the Proof Silver Ikes has started to get a light hazy halo effect around Ike. So far, I haven't had much luck capturing it very well in a photograph.

Some of the others have some slight edge toning. Some are pretty much un-affected.

For longterm storage, I do recommend GemVelope, if they are still available somewhere.

I got turned onto them by Tom Reynolds, who is a large cent dealer. They work fine for copper, too.

Never used 'em for long-term coin storage, but I have some coin show medals in paper envelopes from some 25+ years ago. I'd put 'em in a box in a closet and forgot about them until recently. Some of them have developed nice toning - Preussen

Scroll down a few posts for Rod's contact info.

This is several years old, so I don't know that his pricing is still valid.

He used to charge about $25 per 100 for the 2x2" cotton pouches. I keep all my raw, virgin unc. coins wrapped in jewelers tissue (anti-tarnish) to further prevent sliding, and then slipped inside of the cotton pouch, and the inside of archival envelopes.

Rod has all this gear except the "archival", i.e. sulfur-free, envelopes.

Here's a source for envelopes.

You'll get better results if you "seal" in the gases. ie., staple the 2x2 envelope inside an ordinary 2x2 cardboard/glassine window holder.

Oh, I did not know you could get hairlines from paper envelopes. I store some of my circulated and low grade coins in envelopes 2x3's from staples. UGH. My higher end things I store in mylar flips.

I did notice that my silver eagles did develope some periferal toning.
