Vinyl holders w/ PVC?
MKW
various coin covers and postal covers that came in vinly pages...items
that are important to me for sentimental reasons. Some of the vinly
holders have sweated over where the coin blister is and overall they
have developed an oily film in some areas..although very light. Is
this bad or is it normal for vinyl to sweat an oily substance?
Mr. Jaggers
First of all, PVC *is* vinyl - specifically, polyvinyl chloride. PVC is a
fairly rigid material that is often softened to give it pliability and
flexibility. Some coin holders have the chemical softener, some don't. If
they have it, the chemical will leach out and harm the contents. It sounds
as if that is what has happened in your case. The damage is irreversible,
so the sooner you get the contents out of those holders, the less damage
there will be.

PVC softner in them?

I think those are made of polyethylene, but you should verify this
independently.

it depends on the quality of the plastic which determines how quickly
they breakdown.
This is actually one of the biggest health threats of our generation.
The plasticizer BPA has been linked to dozens of genetic conditions
and serious studies have been done. If you want to get sick to your
stomach, do a search for "epigenetics bpa", there was a COOL
documentary on Nova that showed the effects of BPA on mice and their
offspring. (Most plastic containers leach BPA into whatever they are
holding)

While at the Toyota dealership getting my recall taken care of the other
day, I picked up an ancient issue of Time magazine and read an article about
epigenetics. The experimentation on mice was mentioned there, and it's
pretty scary stuff. I'm glad we know about it, though. Unfortunately,
there will be some who will go to great lengths to suppress these findings
of science, as has become so chic these days.

Well, oly will be the troll here and point out that new baby type
people are still being pinched-off right and left. Regardless of BPA
or atrazine (a very popular substance here in corn/maize-growing
country) or dozens of other substances.
Plastics make for better life, cheaper food, etc. Also gotta say that
without various plastics, things like my angioplasty probably wouldn't
be possible.
All the hullaballoo about plastics is just that much MORE psuedo-
intellectual mumble.
Of course, put your valuable coins into quality flips.

Mr. Jaggers
Oh, I don't know that I'd classify your post as trolling, mon vieux.
Misconstrued, maybe, but not trolling. Nobody here has suggested that
plastics are evil. Compared to the plastics that were around when I was a
kid, today's products are magnitudes better. But, if there are nasties in
them, shouldn't we do what is necessary to eliminate the nasties and make
the products even better? Science is a process, not a destination, and
there are no incontrovertible conclusions anywhere within it, only tentative
ones. Scientific theory changes as new information is learned. Your
admonition to use quality (read: more expensive) flips for our coins shows
that even *you* are aware and appreciative of the findings of science in
that regard.
Now, about all the media hullaballoo about Toyotas...

Science doesn't have a lot to do with it, experience does - I am old
enough to have owned "Harco" coin albums in their original
incarnation, and their "flesh" was 100% pure drippy PVC. I've seen
very nice sets of Walkers and Franklins turn pickle green in those
things, and I'm not the person who goes out of my way to find
examples. "Safeflips" are best.
Now as for Toyota, that recall stuff has ZERO to do with engineering
or science. It is a financial story - Japan pulls back just a teeny
tiny bit from buying our dubious Treasury and Agency bonds, and
Washington flexes its muscles and says "Hey, do you yella fellas want
to sell your stuff here in the U.S.A. anymore???". That's what that's
about - Toyota is another financial "hold-up" or "stop-and-rob" of the
long-suffering Japanese savers.

paranoid as usual...
Mr. Jaggers
Science has everything to do with it. I can't help if the media
sensationalize everything. With very few exceptions, they are just as
ignorant of science as their audiences, but have the additional motivation
of profit behind their activity, so they'll say anything to get your
attention long enough for you to stick around and see what their advertisers
want you to see. The media also lack peer review. But I am not going to
ignore science just because I don't like the scientist or the channel where
his research results are presented.
Agreed, Saflips are the best. My entire world collection is housed in them,
even the coins I paid only 5c for.

The chances of experiencing spontaneous acceleration in a Toyota are smaller
than getting hit by lightning. Once again, it's a media campaign, spurred
on and more importantly, financed, by people who have a bitch about Japanese
products and stand to gain from Toyota's fall. I know politics when I see
it.

Well, I will be a rightist Luddite with what I think about "science"
in the first few years of the 21st Century. No need to go there at
length.
You can call it politics, but in my view, "finance" has taken on a
zombie pre-eminence nowadays in America. It is really neither a
right, left or centrist thingie. Very few Americans are working very
hard at all, and all parties - government, corporate and individuals -
need another loan. Americans of all political views need another loan
very badly. Tommorrow we will need another loan too. And the day
after that. No loans??? The game of musical chairs stops.
You won't give us another loan??? You're toast, Mr. Foreigner-type
person.
Lots of Americans who think they are independent are actually totally
dependent on some government or corporation floating another loan(s)
so the bi-monthly or monthly checks won't bounce.
Zombie "Finance" is pre-eminent in today's America. It's the whole
game.

FWIW, I got a nice early British Trade Dollar XF/AU with lustre this
week (1898 Bombay), plus some circulation quality examples of the
Northern Marianas Quarter Dollars, both P & D mintmarks.
Those quarters went straight into the Dansco albums.
