Question on Archival Quality Vinyl Flips vs Museum Quality Flips

Plus I can flip it, use as a golf ball marker, and get a somewhat tactile feel of the roundness of the coin and still get a very good look at the surface with a loupe, if I want. Try any of that with the coin in a card board 2 x 2 or vinyl flip. For long term storage it is the way to go for sure.

I know very little about them, but I wonder what the future will tell us about the black foam/sponge holder in these airtights. Don't know if they use plasticisers or not, or if that even applies for this material.

Any thoughts on whether these could degrade and/or harm the coins over 10-20 years?

 

Many years ago I used cardboard 2x2s and flattened a lot of staples. I never really liked them, they were just cheap. I switched to SaFlips and have been using them for many years now, and I've never had problems with them. After reading Doug's @GDJMSP analysis, I am now going to switch to Airtites. I have one immediate issue with them. I need to research them to see if hammered coins will fit in them because so many have somewhat irregular shapes. If anyone knows of a simple solution to that issue, please let me know. @GDJMSP , thank you for your analysis and comments.

Edit to add: Also, are there albums that will easily hold Airtites?

 

C'mon...should I pay $5 for $1 worth of coins?

 

Nunya dang business.

 

Thank you, sir! Much appreciated.

I don't think anyone has touched on another real culprit for spots. Dust. Dust specks (i.e., environmental contamination) can get onto a coin from any flip, slab or other holder if it isn't completely clean when the coin goes in. And the dirt can come in with the coin, so that has to be completely clean as well.

My recommendation is that the owner look at the coin in ANY kind of holder from time to time to make sure it isn't changing for the worse.

If you're not interested or willing to look at your coins from time to time to preserve and enjoy them, I suggest that you sell them to someone who is.

 

Nope, there were pinholes where the black was, most likely from staples.

 

Indeed. Some good points on the cost perspective. I have most all of my 300 high-end raw Morgans and Peace $1, plus another 200 or so Walkers, Franklins and Washingtons in these and similar of Airtites and Guardhouse, etc. capsules...some have the black retainer ring and others not. When I was at the ANA Museum in CO Spgs recently, bought several 10-count boxes of the Guardhouse capsules for 38.1mm $1 and for halves at $3.95 ea...just 40c per capsule. That said, I've had many other coins of less conditions in Saflips for years...rarely have to remove them or shuffle around, etc., but check them periodically and no problems.

 

who would staple in the middle of a flip?

 

Still can't believe no one has mentioned this for safe storage of 2X2 flips. Purchase a Dansco 7000 album. It has 6-7 pages that hold 12 flips per page. Don't forget to purchase the protective slip cover to provide environmentally controlled conditions. Your flips are protected from the environment and will keep at least 7-10 years. After that purchase another slip cover.

 

I have a few Löser which are too big for my 2 1/2 x 2 1/2" (6.35 x 6.35 cm) safety flips. I cannot find any larger ones in the U.S. without PVC. Does anyone know where one can get 3 x 3 or 3 1/2 x 3 1/2" (7.62 - 8.89 cm) PVC -free / plasticizers free (thank you, GDJMSP) Coin Flips ?

 

Perhaps @cpm9ball might know of something. He has a lot of beautiful medals and must have a way of storing them.

I don't understand how. The staples are at the edges of the 2x2s, not near the middle where the Mylar is. Do you mean it happens when removing or inserting a 2x2 in a box?

Actually, I'm now leaning towards an earlier suggestion of putting empty installed 2x2s between each coin in my boxes.
