are vinyl pages safe?

I am planning to buy a Dansco stock coin ablum which has 9 vinyl pages that holds 2X2.

My questions is: If 2X2 are stored in vinyl pages, will there be any damges to the coin?

are there any pages for 2X2 that is PCV-free?

thank you very much for all info!

  • I dont know about the Dansco specifically, but I try to keep coins away from vinyl and staples.

    I have used the polyvinyl pages for years with no PVC contamination on the coins in the cardboard 2x2s.

    If I remember correctly, mine contained a slip of paper which indicated that they are pvc-free. I've used them for several years with no negative results. It's great for beginning collections and for odd collections for which there is no book. If you upgrade to a different storage system later, you can recycle your book for your next project.

    I avoid PVC products since they give off gas/vapors that can damage coins even when they are not touching the holder. Can you smell a new shower curtain? Polyethylene coin sheet should be safe for your 2X2's.

    There is no such thing as pvc free vinyl. Vinyl = PVC. That said, there are two types of vinyl/PVC. Plasticized or soft vinyl is the product that has long been used in the industry and the main culprit in in PVC damaged coins. Soft vinyl flips are still actively used today by many raw coin dealers who prefer them due to their being soft and flexible. Unplasticized vinyl (or UN vinyl or hard vinly) has low levels of plasticizers. This vinyl is stiffer but still not as stiff as mylar. Unplasticized vinyl is often marketed as "archival", "safe" and even "non PVC" but it is still made from vinyl (which is short had for polyvinyl choloride which is abbreviated PVC). There are studies that show that unplasticized vinyl is safe for coins under normal circumstances and other studies that show it is not, especially under excessive temperature or pressure. No form of vinyl is considered archival by museums or other similar organizations.

    Unplasticized vinyl is marketed under brand names to make it appear safer than perhaps it really is. For example there are SuperSafe and Safe-T brand flips that are made from unplasticized vinyl. Many resellers and dealers are confused and refer to unplasticized vinyl as "non-PVC".

    Combining unplasticized vinyl with something else between it and the coin (e.g., a 2x2 flip) goes a long way to eliminate risk and is probably okay for inexpensive coins. However, one issue with vinyl is outgassing and the gas could enter the flip so you are not completely safe.

    In short, use this guide to keep them straight and pick a product that works for your appetite for risk:

    soft vinyl = high risk
    hard or unplasticized vinyl = low risk (especially if not in direct contact with the coin)
    mylar, polyethylene, or polypropylene = no risk (at least from the plastic itself you may still need to worry about other aspects of your particular storage approach)
