<p>[QUOTE="leothelion, post: 24739960, member: 10198"]Great article for the collector seeking the ultimate collector's coin with the very earliest die state strike from the very first pairing of working hubs and dies!

For example, a Jefferson nickel with an overall mushy strike, yet the steps are in full detail. Where the high points of a working hub get hammered out but yet the step area remains unaffected and eventually they will start to fill in with the metal that was meant for all those once sharp details; deep hairlines, top of windows, square top digits, and letters and so on. It's like, the step area in the die acts/functions as a reservoir to take up the metal that was meant for all those hammered-out details to prevent a die from cracking.</p><p>Words that I have used over the years to describe this effect; phenomenon, lopsided, displacement of, transference and the more comical terms, the boomerrang or the ballooning effect where as when one area of a coin deflates, an other will inflate.</p><p>Coin that have a poor, flawed, mushy strike yet have 5 to 6 steps, I have termed such coins as having compensated steps.

The volume of the coin blank and the chamber remain the same for every strike of a coin so when the metal has no place to go, the blank is subjected to higher coining pressure resulting in higher compaction. The metal doesn't simply vanish as the details slowly fade during the life of a die.
