<p>[QUOTE="desertgem, post: 3632045, member: 15199"]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[/QUOTE]</p><p><br /></p>
