Message:: [QUOTE="Fred Weinberg, post: 3205893, member: 86437"]1. (Not weak strike,) but Metal Flow,    towards the clip's void area. The     striking pressure of 65-75 Tons    forces the metal toward the path     of least resistance, usually up into    or down into, the dies, thereby     creating a coin.  In the Clip Case,    the metal doesn't do into the die    recesses, but instead flows outward    toward the void (clip area, showing    the metal flow. 2. Blakesley Effect opposite the clip.    This will show on the vast majority    of all clips - curved, straight end,    and ragged. 3. Cut And Tear marks - the gang punch    that comes down to 'punch' out a blank    only goes thru the strip 51% - that's the    'cut' mark; the 'tear' mark is the blank    being pushed down thru the strip, and out.     This only shows on curved and some straight    end clips - if you look inside the curved clip     of any coin, you'll see a smooth area, and a    bought area (inside) - that's the Cut and Tear    Marks I refer to. Hope this helps a bit.[/QUOTE]
