Message:: [QUOTE="bhp3rd, post: 831036, member: 16510"]Well I've looked very closely again at this 87-D also I have seen this thousands of time in the past.  I also have thought about this now for 2-days. What about this:The area of the encuse doubling (87) is perfectly centered on the raised mound of planchet material with the regular struck "87".  Mike says this is the die face where it sunk in.  So it has to do with the raised area pushing up, (thickening, puffing up) exactly where the "87" are located.  For whatever reason, die fatigue, to much pressure or to thinly rolled planchet, the movement of the raised area between the planchet and "87" in the die are to blaime. The encuse area of the "87" is directly connected to the properly struck "87" right?  So the mound in this case under the "87" as the coin was struck pushed and worked as a wedge slightly kicking it out just in an instant.  In other words when a coin is normally struck with an even (normal) planchet's surfaces the "87" in this case strike up and finish staight and single in appearence.  If struck on a mound, raised or rippled effected area the image (because there is now simply more material beside it) has to kick out and in these cases the kicking out leaves this secondary encuse impression.  In a way the area of the "87" was struck through more material and on a slant or bubble - the encuse "87" dug into the extra material leaving an edge of an encuse design.I bet if we look closely in that '87" the "west to east' portion is much deeper and defined than the "east to west" portion.  The die had no choice but to mimic the "87" because of the pushed up material and uneven surface.[/QUOTE]
