<p>[QUOTE=&quot;ToughCOINS, post: 7968828, member: 20480&quot;]Oh sure . . .&nbsp; Now I’ve got to build a porch to crack my slabs <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie8" alt=":D" unselectable="on" unselectable="on" /> !</p><p><br /></p><p>This is an elegantly simple way to break a slab.&nbsp; I have only one misgiving about using this approach.&nbsp; </p><p><br /></p><p>The slab starts to break where it is most stressed, and the crack progresses less predictably.&nbsp; While it seems unlikely, I’d hate to have a resultant sharp edge, pointing toward the coin, “stab” the coin as the holder folds over underfoot.</p><p><br /></p><p>When I crack a coin out, I wrap it in a paper towel, long edges exposed, and place it end-to-end in a vise.&nbsp; Then I wind on the vise until I hear the halves of the holder buckle, typically in opposite directions, allowing me to easily pry the two halves apart.&nbsp; Sometimes both sides buckle in the same direction, and one ends up breaking, still providing me with prying access.&nbsp; </p><p><br /></p><p>The major benefit of using the vise is that the extent of breakage is limited to the stroke of the vise, and is thus very controllable.[/QUOTE]</p><p><br /></p>
