Does every old envelope have sulfur in it? How can you tell?

I should have put a smiley after my reply. I don't know nor do I really want to.

I think this is the finest definition that I have ever heard regarding toning. Since I began studying numismatics I have never seen a better one. Thank you for a great analysis!!

 

I used 100% rag covers for my first flight, ship cancellations and 1st day covers.

 

I found this thread looking for what causes toning and what accelerates it. I purchased two sleeves of 2000 Silver Eagles back then from a TV coin show. They are 20 to a sleeve, soft plastic US mint tubes. I take them out maybe once every 5 years to look at them. About 10 years ago I noticed 2 or 3 had started to get some toning. Maybe they were enders, I don't know. But the tubes are sealed airtight, it requires some effort to get the top off. But that's not why I came here, I have a question. If someone 20-40 years ago lightly abrasively rubbed a coin, will toning form a new patina and fill those tiny hairline gaps? (I am talking about coins in general, not those Eagles). Or will it just mask and hide them at 30X magnification? I don't think TPGs use higher magnification for grading, just attribution?

 

It is quite possible to have a 're-tone' hide an earlier cleaning but depending on the rarity of the coin, it seems the TPG companies have x-ray eyes........

 

Thank you. But I want to hear what the Maestro says about this. He is a fountain of knowledge. And I'm quite sure he is experienced in the black arts of coin sorcery.

 

I get it. But that’s cheating the world

 

Say who

 

I'm glad to see someone else is beating the dead horse with questions besides me. The owner of this site (I think he owns it) has laid this whole argument out in this very thread. If a tree falls in the forest, and no one sees or hears it, did it happen through nature or did a chainsaw cut it? No one knows. It makes for a great debate. Me personally, I don't care for ridiculously toned coins, especially dark nasty abominations. The rainbow ones are incredible but I don't trust them either.

 

Now that Ben is SWEET

 

Save the envelope money.
Put the piece in a used Taco Bell napkin, and place it on the oak window that is sunny.

 

Wrap your coin in a taco bell napkin with some match heads around it and put it on a window sill that gets some sunlight. It will tone faster with the sulfur match heads.
Check it every 2 to 3 months.

 

I covered that....do I have to invoke Boot Camp Rules to prevent tardiness in the future?

 

Some are just ugly coins

 

What a western great lakes girl does in finding coins, may not be what the eastern side does. That is what makes coins fun.

 

And all this time I thought you were a dude. I should have known, an ex-girlfriend of mine used to use that expression all the time, "a pickin and a grinnin.....

 

If someone wants to check for sulfur in objects the simplest is using lead acetate test strips.
