<p>[QUOTE=&quot;imrich, post: 790048, member: 22331&quot;]<b>Without explaining the physics of reversing the encapsulation process, I can state that you will not harm the coin if you carefully place the coin holder lengthwise between the jaws of a 5&quot; (max. jaw opening) vise with preferably steel jaws, so that the holder is unsupported except by the jaws clamping, and slowly clamp the holder until you hear a cracking noise. The maximum bending moment is at the center of the holder, so the opening will often start there. Remove the holder, and rotate 90 degrees, clamping on the narrower dimension of the holder, again slowly clamping until hearing the cracking sound.&nbsp; Rotate the holder in 90 degree increments until the holder finally generally breaks on 4 sides (usually less than 360 degrees). While the holder is clamped, carefully insert the end of a flat screwdriver into an opening in the holder side, and slowly rotate the screwdriver handle axially, 90 degrees. It&#039;s preferable to place a clean cloth under the holder in the jaws, to catch the coin if unprepared when the holder finally fails. This process applies virtually no shock to the coin, while stressing the case, causing a fissure at the &quot;parting line&quot;. The ease of removal will vary between Holder designs, but this process works for virtually all holders, without coin damage, because the holder is placed in bending, causing shear, where the coin is placed in compression against a material with far lower allowable compressive strength. </b>[/QUOTE]</p><p><br /></p>
