question on coin holders
 

Greetings, I have just recently become a registered user, but have enjoyed reading the forum for quite a while. I have a question about the air-tite coin holders which have a black gasket in them. they can be seen at apmex with this link;

I have read in these forums that certain plastics, especially pvc can harm the appearance of coins stored in them, I am storing a 1oz eagle, buffalo and hopefully soon a maple in these containers. Does anyone think that long term storage with the soft rubber ring may be harmful?

I would like to know this as well. Currently, I have my gold coins in said holders.

Silver will straight-up tarnish from these rings. I cannot say that all rings fall prey to this caveat.

Re: question on coin holders
 

What about gold? Should I put my gold coins in the air-tites that do not have the ring? I didn't even think about this problem.

Re: question on coin holders
 

Fact: Most airtights aren't.

Re: question on coin holders
 

Makes sense.

BUT, which would cause the least amount of damage? Airtite with ring or Airtite with no ring?

Re: question on coin holders
 

I would not store my silver coins but the gold should not be a problem. Would look for exact size capsules without the insert. Maybe they are fine but I do not trust them.

It's the plasticizers (softeners) used in PVC products, particularly soft vinyl flips, that are known to damage coins over time.

Quote from Air-Tite Holders, Inc. website:

"Our holders are manufactured through the process of injection molding using virgin acrylic plastic that contains a non-yellowing agent, which helps maintain the clarity of the holders over time. The white or black ring/spacer material is produced from a cross linked polyethylene, which is a plastic material. The materials used in the production of our holders and rings are totally inert and PVC free."

Listen to this experienced GIM'er.

However if you must have them::yes:

I think AMOS.COM has coin and stamp supplies.

I know you can find them via "COIN WORLD MAGAZINES."

You really do not need holders for bullion coins; the tubes are fine.

Just "add" those SOFT PEANUTS to fill the voids in the tubes - that the shippers use in packaging almost everything.

I put these Maples in about a year and a half ago. Most are still looking good, but some do show slight spots, and I presume they will get more pronounced as time goes on.

Re: question on coin holders
 

what kind of spots exactly?

Re: question on coin holders
 

The spots are strange....you know when you breathe on a mirror or piece of glass and it leaves that little ring of condensation? They look like that, but tiny, and random. Some have one or two, some don't have any.

I put the Maples into the Air Tites with gloves, so there shouldn't have been anything coming into contact with them.

Re: question on coin holders
 

Are these the same Air Tites that APMEX sells? If so, I think I am going to swap mine out for the ones without the black ring in fear of the same thing happening with my gold coins.

Re: question on coin holders
 

Has anybody else experienced problems with the Air Tites with the black ring?

Woah, man, totally off-topic, dude, but... due to the perspective of Jekyll photo, it looks neat when I scroll this page up and down with the mouse wheel. Try it out!

Re: question on coin holders
 

people say that its the "plasticizers" in the plastic (even if its advertised as non-PVC) that causes yellowing. so, couldn't they use mylar plastic instead? doesn't mylar resist yellowing?

I would highly cardboard protected with mylar inserts::

Or these mylar containers:

Does anyone disagree?

Re: question on coin holders
 

"Plasticizers" are the compounds added as softeners, not the plastic itself. Acrylic is a plastic, but does not contain plasticizers.

Most safety flips are OK. Air-tites are OK (with or without ring). Cardboard/Mylar "fold-and-staple" holders are questionable IMO. The Mylar is safe, but the dust from the cardboad may be a problem over the long run.

Re: question on coin holders
 

Air-tites will not harm gold coins. I doubt they even harm silver ones, it's the aforementioned lack of air-tightness that likely causes problems. With gold (or palladium/platinum) this is a non-issue.
