    Your entire coin has been exposed to extreme heat after it left the mint. The coloring is an obvious giveaway. You don’t need to poke it on one end for it to bubble on the other. I’ve seen dozens of clad coins that have been damaged with heat. Sorry, not an error.

    To be a Bubble or not to be, now I consider this to be a “raised” question?

    I have read several times that the heat generated by the strike process wasn't significant enough to cause any damage on the coin. I even recall many years ago, seeing a photo in one of the 60's era of a worker catching a bunch in his hands from a machine. Don't remember if he had gloves or not. Denver mint sticks in my mind? and Gas from what~air? Wouldn't the minting pressure push down any bubble with such low pressure? Jim

    I've felt coins as they've been struck and ejected,
    at the Philly and Denver Mints.

    The coins are warm, but not hot, in your hand.

    I have a problem with the quote. The amount of gas and origin, heat level, pressure, etc. If the air was a very small distance under the surface, I could expect the air(gas) could be compressed during strike and then during ejection, the small copper wall of the top of the bubble would be so thin it allowed it to pop up due to the softness of the copper alloy unable to withstand the pressure. IMO, Jim

    One more time. The issue on your coin is not an Occluded gas bubble mint error. What you have is damage caused by extreme heat. Somehow the heat caused the clad layer the bubble up over the copper core in the spot. How? I really don't know. But I /we have seen dozens of examples just like your coin over the years.

    Your coin has all the characteristics of a bubble between the clad layers caused by heating after it left the mint and none of the characteristics of an occluded gas bubble. It is not an error and is only worth face value.

    In the other thread where you posted this coin, a top dealer and error expert gave you a brief explanation of why this is damage. This is the guy that the TPGs go to when the need an expert opinion on error coins. I'm not sure where you can get better verification than that.

    Look, we're just trying to save you a little time and money. This group would love to confirm that you had a real error, but many knowledgeable people have given you accurate answers. Just trying to help

    Once again your coin is just damage. The damage occurred after the coin left the Mint. It is not a Mint error. It is not in occluded bubble. Someone with too much time on their hands applied heat to the coin. This is what causes the pump that you see and it is considered damage. Please do not waste your time and money on this coin.

    To “Bubble” or not to “Bubble”
    Appears this subject is becoming a “Heated” issue of sorts, Lol

    You’ve gotten your verification. It’s been heat damaged after the mint. Please don’t waste your money. But if you must, please honestly come back here and admit it when it comes back as damaged.

    Cool, a new error to check for! Thanks paddy! Also you were right about the half crown, I finally got it tested and it tested negative. I just figured it would be like the modern US clad style.
