<p>[QUOTE=&quot;walterallen, post: 568827, member: 4068&quot;]I cringe every time I hear someone talk about using a saw/ band saw to open a slabbed coin. I work with machine tools of all types and sawing is a violent operation for plastic.</p><p><br /></p><p>My advise is to find a bench vise. The bigger the better. </p><p><br /></p><p>Put the holder between the jaws edge wise. </p><p>Close the vise just enough to hold the slab tight.</p><p>Carefully and ever so slowly close the vise until you heard a crack then stop.</p><p>Open the vise and orient the slab one quarter turn and repeat.</p><p>Close only until you hear a slight crack.</p><p>Open vise and orient again one quarter turn and repeat.</p><p>You will start to see the edge begin to seperate.</p><p>This is when you must pay close attention not to allow the coin to drop to the floor.</p><p>Make sure you have a hand on the slab as you release it from the vise.</p><p><br /></p><p>Slabbed coins are sealed by a process known a sonic welding. You must break this weld along the edge of the slab in order to free the top from the bottom. Patients is a vertue. I have freed many coins from PCGS and NGC holders using this method nad have had no problems. Just go slow and pay attention.</p><p><br /></p><p>Good Luck no matter what method you choose to use.</p><p><br /></p><p>Allen[/QUOTE]</p><p><br /></p>
