I am thinking of putting a set of Franklin's in 2 X 2's then in

Cowens Vinyl Sheets. I bought some of these sheets today but when I got them home it seems they have a oily feel to them.

When I bought them I asked the dealer if they were PVC free and the answer was "These are Cowens, they're the best for coins".

Even if they are pvc free, will the "oily feeling" hurt the coins?

Can it seep through the 2 X 2 ?

Is the oily feeling in my head?

Is there another brand of sheets I should be looking for?

To be truthful, I usually find pages made especially for coins to be the worst, because over time, they dry out and become brittle. I don't know about Cowens, but I use Ultra Pro sheets for slides instead.

I also use photographic slide album pages. They're solvent free, acid free, and they degrade much more slowly than "coin pages".

The solvents and plasticizers that are creating the "oily" feel can't usually work their way completely through a good 2x2 film (not after at least a couple of decades, anyway). But they can soak partway into it over time, making the film sticky on the outside which in turn makes the 2x2 difficult to take into and out of the pages. This process is accelerated if the pages are "squeezed" together for prolonged periods, either by stacking a huge pile of albums one atop the other, or by jamming too many pages into a closable album and forcing it shut.

I recall once going to a dealer stand at a coin show where this "solvent transfer effect" was so bad, and the 2x2s in their stockbooks had become so sticky, that the dealer handed me a dud credit card and a screwdriver so I could prise the coins free of the album. It's not a way to impress customers.

AND I full well know that feeling. I too have attempted to pry out a coin from some of those sheets and they were as if glued in place. When a dealer has to hand you tools to get a coin out, you have to wonder just what is happening to that coin. And what if you slip and it runs accross the face of the coin? At one coin show a dealer had to cut the coin out with a knife.
I know there are many manufacturers of those sheets and the ones I have used so far are OK, but I still wonder about the future.
