Coin protection - what are these things called?

I received a nickel a while back that had a very thin plastic holder around it. I mean, THIN. it hugged the nickel completely. It is in two pieces. I do not mean something like an airtitie. Lets just say, at first, you couldnt even tell there was anything around the nickel. I didnt know it was even there until I tried to put it in a Dansco.

Am I making sense? Probably not. But tell me what it is anyway. I want more.

Saran wrap? But yeah I don't really know what it is your describing.
The only thing I use to protect my collection is these (and some airtites)

 

You may be describing a "cointain".

 

I tried aluminum foil, but that wasn't it either.

 

Hmm, close! Those cointains appear to be hard plastic. The one I have is soft. Like a contact lens. I will message the cointain people and see if thats it.

 

You are making perfect sense! I haven't the slightest idea what you mean!

All joking aside, I've come across similar coins and medals before.

This photo describes a recent batch of coins. The 1946 Canada nickel is inside a cointain.

Can you guess which coin in this photo I got for free?

 

The JFK!

 

The nice red Lincoln cent was free.

 

I have received several on coins purchased at currency shows. I'm not overly fond of them because with a little pressure they come apart. I am sure they don't protect the coin from contact damage because as stated, they are soft. Plus being thin they always make me wonder if they are sealed properly. They are much cheaper however, so if soilage is the only issue, they may work for you.

 

Probably a cointain , great product .

 

I wish Cointain made albums to hold their capsules. I tried to ream holes in a Dansco larger but cardboard doesn't drill well with large bits. Maybe a forstner bit could do it cleanly

 

These type of bits will only damage the page. Large bits are called silver and dimming bits. Not made to enlarging holes. Forstner bits are made to lathe holes in wood and again not made to enlarge a hole. Rotary files will work if you know how but won't leave as clean of a cut on the paper.

 

Cointain it is! Thanks.

Well, the ones I found are "KoinTain Coin Capsules".

 

They been around a long time , Even the Smithsonian uses them for that natural look .

 

Hey! someone who knows carpentry! The outside cutting edge of a forstner hangs a bit lower than the chisel part of the drill. I figure if I take all the album pages and firmly clamp with a piece of pre-drilled Lucite on top, lined up and clamped to the drill press, that that will alleviate tear out.


The Cointains I have measure .782 loose ... 20mm is a hair to big - 7.87

25/32nds = .781 which is perfect. Problem is that they call a 25/32 forstner also as a 20mm! I guess I could mill one down.. plus there is a bit of a bevel to the top and bottom peices of the Kointain.. It will have to go on the "some day" project list for now.

I really do like the way the coins look in the album using the Kointains - and, it has to be a much better superior way to store the coin in an album

 

You certainly will avoid problem hairlines cause by the sliding plastic protectors. That's a BIG plus.

 

I finally just got the vinyl pages with the p[ockets for 2x2s and keep them in binders.

 

I don't have any Cointains, so maybe this is a dumb question, but if they're soft like a contact lense, I'm assuming they're using a plasticiser to obtain this pliability, so isn't there PVC's involved here?
