There are a few different materials that coin accessories or storage products can be made of. PP: Polypropylene. Used by The Purple Penny, Ultra Pro and BCW who all make 2x2 coin pages. COIN SAFE PET: Polyethylene Terephalate. Formerly known as Mylar. These are what Saflips are made from. COIN SAFE PE: Polyethylene. Most zip lock or food use ie. Glad bags are made from this. COIN SAFE HDPE: High density Polyethylene. This is the hard plastic. Lighthouse make capsule and slabbed coin pages out of this. COIN SAFE PVC: Poly vinyl chloride. Steer clear of all of this stuff. NEVER EVER EVER COIN SAFE Some accessories advertise "softener free" but are still pvc. More info have a read at http://www.australian-threepence.co...ou-sure.html |

There is this test I used a couple of years ago on Lighthouse holders, some no-brand holders, Lighthouse 2x2's and some ziploc bags (not designed to hold food). Here's the thing : I use a glove to hold a pure copper wite (one that is formed by breaking open a standart office clip) and heat it till the colour of copper gets very red. After it, I pierce the plastic stuff I want to test with the hot copper wire and as the plastic melts on the wire, I take it back on fire, see how the plastic on the wire burns. I observed two kinds of fire, one with fiery, bright green (means PVC - STAY AWAY, ziploc bags and no-brand coin acsessories) and two, regular, yellow flame (Lighthouse products). I find it stll useful, if I ever need that PVC testing again. I hope this helps you guys.
I use roasting bags for cooking in ovens (ones that you put whole chickens and turkeys in it) for string aUNC bulk coins.. Any ideas if that's god?.. The oven bags come directly in contact with the food inside a 200, 300 degrees celcius oven.. if they have PVC, all we are eating would be Chloride (I guess) So they're supposed to be safe, aye?

Hi 2old, PVC is safe and stable in solid form, can even be used as water pipes, but when heated and in gas form, it is toxic, you can burn a small-small quantity of it, outside in a well ventilated and safe area, note the color of the flame- yes, but please be very careful NOT to inhale the smoke, it will be coughing time, at the very least.

2old says:
"I asked to be cremated and my ashes spread along a Mexican or Caribbean beach."
just carl says:
"Spreading your ashes on the beach too is rather morbid. Imagine all the Mexicans stepping on you."
So what's wrong with a beach? I've stated that some of my ashes go into the sea, as for the rest I don't give a ****. When you're gone you're gone. But the idea of some of my molecules eventually meeting with some from Ghandi and countless others appeals to me.
just carl further says:
"Even though the banks interest rates are low now, in just a few hundred years even a small amount would be worth something."
Yea, let's hope! That is if we (multi-corporations, banks etc) don't s***w it up for future generations.
Now that's what I call being morbid.

I gotta go with 2old. I want to be cremated when I go. My ashes would be very much at home in Mexico I spent a lot of years there, and feel like I'm home again when I visited. Of course I am not planninyg on going right away. I'm too young! I'll be 84 on Hallowe'en, and have always said I want to live to be 125, so I have a few uyears to go, if my wish is fulfilled.

Yes and No to all that. PVC is really not the culprit as noted. Even the melting point is 212 degrees. PVC is a PolyVinyl Chloride substance. Poly = Many and Mer = Parts. PVC is a multi elemental covalent organic coupon. Components are Hydrogen, Carbon and Chlorine only. That is C4H6Cl2. As already noted PVC normally can not harm you and yes it is used in piping for water in many homes and for water. It does not decompose easily under most normal instances. And yes, if you burn PVC, it will give off the Chlorine as a gas and that could well damage your nasal passages as well as your eyes. Again, it is the additives that manufacturers add to PVC to make it more flexible that is the culprit. Note at any hardware store the PVC piping. It is very rigid due to none of those Plasizers added. It is the Phthalates added to PVC that tend to leak out and create all kinds of problems. However, as long as there are such things as Old Wives tales, people will run around saying how PVC makes the world turn Greennnnnnnnnnn. |

Just Carl speaks the truth.  The plasticizers used to soften PVC are what is bad for coins. |

It isd a good thing that PVC is safe for water delivery, because if it wasn't, I sure did my self a dirty deed. I just finished plumbing my mogile home with PVC!  Dick |

Now if you ask the PVC fanatics about that they'll tell you that you too will turn green soon. HMMM, wonder if that is why the Incrdible HULK was Green? |

Interesting thread. I was also told that if they smell like a cheap shower curtain you'd get out of the bargain bin from Walmart, then its laced with PVC. |

Again more of what is called old wives tales. In most instances if shower curtains smell it may well be from many other things. Like mildew from being stored in a damp place. In many stores mice too use some places to do their bodily discharges and that too smells. Note how many other items have an odor from storaging if you just walk around any Walmart Store. Around me it is mostly an odor of the employees. |

Yes, the odor of a new shower curtain is due to PVC which is the primary composition of the cheap shower curtains. Attributing the green slime to PVC is not an "old wives tale", it is fact. Only the PVC flips contain the phthalate plasticizers and that is what causes the problems. The plasticizers leach out of the PVC plastic over time and create a hydrochloric acid sludge, aka the dreaded "green slime". Mylar and other archival-type flips do not have phthalates added and they are perfectly safe for long term storage. This is what a coin looks like after long term storage in a PVC flip-  |

The plasticizers leach out of the PVC plastic over time and create a hydrochloric acid sludge, aka the dreaded "green slime". Partially true but not all shower curtains contain PVC and they do still smell. If you go to Walmart, for example, and read the lables of the shower curtains, you may well be amazed how many smell and do not contain PVC. I've heard those stories for a long time. As always my methods are to write down the name of the distributorr or manufacturer, call them, note to them the conversation is being recorded and ask about the possilbe PVC contents. Again if they say NO and there really is, great for a law suite. This is the same with numerous Plastic products. For example many plastic glasses in a plastic container may well smell when first opened and I've found many that do smell. And it is against the Federal Law to have PVC in containers that will be used for food products. Walk down the aisles of almost any store where plastic products are in abundance and you will smell all sorts of odors. As to that quarter. If it was mine, I'd really want to know just what that stuff really may be. |
