<p>[QUOTE="Hoky77, post: 4112478, member: 97374"]I looked around for a article I have somewhere that addresses the weakness in many of the CuNi Cents but I couldn't find it. To my best recollection it seems that the hardness of the CuNi alloy was very hard on the dies and at some point the clearances were loosened to extend the die life. I believe it was stated that the weakness in many of the features of the coins struck after this change in the process is attributed to the increase of the space between the hammer and anvil die. All this being said does not negate the fact that the dies were also periodically greased causing the struck through errors. It would also explain the gorgeous fully struck examples in existence that would have been struck prior to the change in the process. I assume this applies to the later years (60 thru 64) or the whole life of the Copper Nickel Cents. I do know that it is difficult to find any of the IHC years that aren't mushy.[/QUOTE]</p><p><br /></p>
