hey guys, I came across some articles talking about how some coin albums contain pvc (in the plastic) that can damage coins if store in them long term. I've got a couple of little albums for 2X2 flips like this... http://www.ebay.com/itm/60-COIN-HE-...em4abb489299i assume these would contain pvc, is the true? i did have some ancients in one but didn't like how they looked, so they arein transit back to storage boxes. is the pvc bad for ancient bronze coins also? anyway, my ancients just left the albums a coupe of weeks ago but I have a small (but growing) collection of modern coins in them now. do I need to get them the heck out? bronze diease, pvc, ....didn't know there was so much to worrow about with coin collecting when I started a year ago! |

From what I've read PVC can react with the metal of the coin and, in the long term, leave deposits such as these (left)...  Personnally I use Saflips, made of polyethylene. I also like the fact that they are more rigid than the usual 2 X 2 plastic flips. When you handle them, the coin inside does not "float" all around (hate that  ). |

I am unfamiliar with the particular 60 pocket album pictured, but I suspect that is made from clear PVC.
Ancient bronze coins in Mylar 2x2's in PVC albums seem to suffer the most. However, all bronze coins suffer. There is an accelerated tendency for them to darken, or even turn black. Best to put the 2x2's in archival quality album pocket pages.
It is a pity to see a brilliant red uncirculated modern bronze coin slowly turn to a rich chocolate color, and loose that beautiful brilliant mint lustre.
Just imagine what a Roman sestertius may have looked like after it was freshly struck!
Before the advent of PVC albums, lots of coins were stored in blanched paper 2x2 packets. The paper was whitened with chlorine, which over time, would gas out. This is one of the main reasons why ancient bronze coins are so often seen with a dark, or even a black patina.
Best not to exacerbate the problem by using soft clear PVC album pages.

I have just chucked out 11 of these type of albums (120 coin per album). They only cost me about $25 each and I thought they were the "Bees Knees" a year or so ago. What a waste of money that I could have spent on more coins  Get rid or yours and replace them with non PVC Archival quality albums, They may cost a bit more but in the long run they will pay off big time  I have just done this and I am now happy that I did it before any damage was done to my collections. Besides the new albums with their flash slip covers look way cooler than the old ones  |

What if you have 2x2 flips that don't have PVC in it, that you place in one of those albums? Wouldn't those flips protect it from the PVC chemical reaction?

Short answer =NO Long answer= Most 2x2's have Mylar windows in them. The Mylar is semi porous and will over time allow the PVC to penetrate through to the coin. The saflips which are non PVC could work but only if they are heat sealed. Either way it would worry me to have PVC anywhere near my coins. So the long answer is the same as the short one NO  |

I got mine from "The Purple penny" in Aus, I would imagine the postage to the states would be prohibitive. I am certain that you will be able to find something similar locally The beauty of these ones is that even the binder and slip cover are non PVC durable plastic as well. Some pics,     |

Hmmm, I am glad this thread got started. I knew about needing to use special flips, but it never occured to me to use archival grade pages as well. Time for an upgrade!

I have the date set from 1937 to 2012 trout1105 => I also have the date set from 1937-2012 ... well, except for the illusive "1947 Maple Leaf Curved 7" ... I have the 1947 Straight 7, 1947 Curved 7, 1947 Maple Leaf Straight 7 ... but that dang 1947 Maple Leaf Curved 7 is my unicorn of that set!! (maybe one day?) Oh, and I really like your coin albums ... perhaps I'm gonna have to rethink my current storage method as well? (too bad, because I've put so much effort into their current homes ... but I guess I should rescue my poor suffering coins? ... man, apparently it's kinda like I've built them a beautiful home, but I've used lead paint, lead piping and asbestos!!)   |

I don't think lead will hurt your coins at all and asbestos only kills people not coins ,I hope you can get rid of the asbestos old Mate cos that stuff is one of the REAL silent killers of the 20Th Century. Your coins will be fine But that isn't the issue here ( They can be replaced YOU cant) get rid of that asbestos Mate (Carefully) |

ok, so I got a bunch of archival quality sheets to my world coins that I can put in a binder. plus I picked up this binder for the coin...  but it seems like the binder is made of your usual everyday binder material...and may contain pvc? if so....are the coins ok if in mylar flips, IN an archival quality non pvc sheet that holds the flips, IN a binder that may contain pvc? or am I worrying about this to much? |
