    I recently got 2 new gold coins that I bought. a 5 peso mexican gold coin, and a lucky gold angel 1895

    Both came in flips. Now I heard they stopped producing PVC flips (at least my uncle told me this) Is this true?

    Gold is anert, malleable, and ductile, gold does not generally tarnish. So will PVC ruin these two gold coins? I don't live near a coin store, should I order cardboard 2x2's online and store those in it?

    And is PVC white and milky or Green?

    I thikn i've seen both

    thanks

    No it is not true.

    To the best of my knowledge PVC will not harm a gold coin - but it won't do it any good either. So yes, you should change the holders.


    It is both. When it first breaks down the substance is an oily, milky white. As it ages it turns green - and then eventually almost black.

    Ya know what - I better re-state this. While PVC should not harm gold - it very well may harm gold coins because they are not pure gold - they are an alloy, usually 90 - 92% gold. And PVC may harm the other metals in the alloy in some cases. But I can't recall ever seeing an example.

    Good point about the 10% alloy that isn't gold. Just about any gold coin should be worth the price of an airtite to protect it.

    Well, I do not have the money to buy an airtight, and there are no coin stores near me. So what can i do? Which flips are PVC and which aren't? I don't want to ruin my coins.

    Air-Tites are less than 50 cents each at JP's Corner They also sell Saflips - no PVC. But a 2x2 will do just fine until you can get either of the above.

    Great thanks. I thikn I might have some saflips, I dont know. Are saflips the ones without PVC and they are hard and brittle? I think i might have maylar ones, do those have PVC?

    thanks

    Hmmm - slow down a little and read " They also sell Saflips - no PVC."

    Mylar contains no PVC and yes they are hard.

    Does anyone really believe this is an honest thread? It's pretty easy to spot a put-on like this one.

    That depends on how you wish to define brittle. Even non-PCV filps are still flexible - they bend. But if you bend them enough yes they can crack. You can't really answer such a broad question.

    If you want non-PVC flips then buy Saflips - it's just that easy.

    Yes, I believe it is an honest thread. I think GCL is a young man who wants to learn - but he also thinks he already knows some things. Unfortunately, he has learned a lot of bad information that simply is not true. Therefore he has a hard time believing it when someone gives him good information. The question is - will he listen ?

    Sorry, PVC damaging gold coins is true.

    Pure gold does tarnish or "melt" under extreme conditions if you aren't careful enough. And here is a link off wikipedia: http://en.wikipedia.org/wiki/Gold Forget gold alloys, that's much useless.

    And a direct quote off them: Gold is a chemical element in the periodic table that has the symbol Au (L. aurum) and atomic number 79. A soft, shiny, yellow, heavy, malleable, ductile (trivalent and univalent) transition metal, gold does not react with most chemicals but is attacked by chlorine, fluorine and aqua regia.

    And if you know what PVC is made out of, it is PolyVinyl Chloride. Now, you can make a final conclusion by yourself.
