[QUOTE="coinjester, post: 528458, member: 6139"]*Do I hear an echo?* Please see the 2nd sentence in post #17. The pre and post war Jefferson five cent piece is composed of 25% nickel. Nickel is extremely hard. As a matter of fact, you and I both know it's the hardest metal composition the US Mint uses for coinage, yes? It tears up the dies like no other metal. Die life is shortened greatly due to this problem, no? When a planchet is struck under extremely high pressure, it causes the metal to heat immensely and liquify to a certain degree in order for the metal to flow into the devices. When a die has been used continouisly, does not the constant flow of metal and extreme pressure have a tendency to cause the metal to build up in the cracks and crevices of these devises and eventually fill in the device? The answer is: 'Yes' Eventually this debris can and does break loose and falls onto the planchet. When a planchet is loaded into the die and a piece of this die fill (the stair case in this instance) breaks loose and falls onto the planchet, image side up, then struck by the die, you mean to tell me that this piece of extremely hard metal debris would not leave an incuse image of itself in the die? I beg to differ. Due to the fact that the error image on the coin is raised, not incuse, this scenario has to be accepted as the only viable way this could have happened until proven otherwise.
