    from PCGS eCollector on Originality and Toning.

    Wouldn't surface haze from a flip be PVC related? Or is this the type of Haze one sees on proof coins in mint packaging after a number of years? If it isn't PVC and happens in a mint wrap, why would it not be graded?

    Secondly why or how would someone artificially add "Haze" to the surface of the coin? I assume it is to cover cleaning or marks,

    Just confusing :p

    Just curious to what "Coin Haze" is. Does anyone have a pic?

    It is confusing, but that's because to them "surface haze" means one thing while to most others it means something entirely different. It comes back to terminolgy as always, and is why it is so important to fully understand the vernacular of the hobby. And to be quite honest, there are plenty of times when even those who should know it inside and out misuse it.

    There are things that can be done to coins that that the average collector doesn't know exist. Like putty to fill hits and abrasions, adding haze to cover or obscure the surface, adding frost to devices, some forms of tooling - the list goes on and on.

    But confusion reigns when one is unfamilar with certain terms and how they apply in the context of coins. Words can have an entirely different meaning depending upon the subject you are discussing. But in general terms, haze in the context of coins does mean like what you commonly see on some Proofs. It looks like an opaque thin film, whiteish and sometimes even bluish in color, that covers the fields and outer edges of the coin. And yes, this thin film can be added to business strike coins in order to obscure the surface.

    Imagine if you will, pouring a little milk on a coin, then picking the coin up by the edges and letting all the excess run off. It will leave behind a thin film on the coin - that is what haze looks like, kinda.

    Thanks Doug for the explanation.

    Doug, thank you. The reason I broke many of my coins out of the proofsets are because they were toning with a haze on them.
    I hate that haze but am afraid to clean them; I don't really want to sell them because I've had them so long (packrat mentality).

    Look at some commercial BU Peace Dollars, I see an awful lot of those with a milky haze on them.

    Understand, but I doubt breaking them out will stop the haze from getting worse. They can be easily replaced, so why not do so before it gets too bad.

    Oh, I thought putting them in an AirTite would stop the haze from getting worse.. if there's a good chance it will get worse then I will replace them.
    Thanks.
