<p>[QUOTE=&quot;Oldhoopster, post: 3223543, member: 84179&quot;]That one confuses me.&nbsp; I could see if a gas bubble near the surface was trapped and when struck, built up pressure that was released when the die lifted causing the “blowout”.&nbsp; As [USER=66]@Conder101[/USER] pointed out, gas bubbles can be retained in a melt.&nbsp; However, if the original ingot had a bubble, I would expect it to be flattened and elongated during the strip rolling process, not stay as a spherical bubble.&nbsp; Therefore, I don’t see how this could be a mint error.&nbsp; Can anybody tell me what I’m missing?[/QUOTE]</p><p><br /></p>
