Can a coin be toned while its inside the holder.....because......

At first I thought maybe there was some anomaly with the strike of this coin's rim but upon a closer look with a stronger magnifier, its the insert inside the holder that looks melted. So....is there a way to heat the coin without heating the plastic of the holder to artificially tone a coin.....like, perhaps a kitchen microwave or use of a laser? Maybe, over time, if a coin is left to sit in the sun on a window sill or a shelf or desk close to a window, an accidental toning takes place. The coin is really sunk in with the insert as seen in photo. First for me to see the insert do this on a coin's rim.

    Maybe induction or some sort of electromagnetic process could heat the coin alone.

    Ok....new theory....your use of the word; decompose helped. The reverse side does not show whats on the obverse so.....I'm now leaning towards when they pushed the coin into the insert, some material got shaved off in the process and that's what I'm seeing.
    Case closed. Thanks,

    I think we all would be wise to never place a slabbed coin in a microwave. Maybe a good lesson to keep in mind.

    Is that melted or decomposed? Or is it simply just the gasket edge overhanging the rim of the coin. They are supposed to have a lip for the coin to set into right?

    Put it on your car dashboard in this heat and see what happens.

    But that is normal I have seen in the holder.

    Coins and holders are subjected to lots of enviromental forces, sitting in a hot car or USPS delivery vehicle for example. Under hot lights during a photo shoot. The gasket is a softer material than the metal or the plastic tomb so it is not unusual for the gasket to deform, discolor, or breakdown differently than the holder.
