I have a coin I plan to remove from the NGC holder (and put it into one of those nice see-through coin boxes I bought from a company in the United Arab Emirates), because somebody at NGC put the coin into the holder upside-down, so what is the safest way to do this? Also, since removal from the holder renders the certification null and void, is it customary to inform NGC about the removal? This is the NGC holder I am referring to:
I use a band saw from the early 30's. Most you can pop open from one cut. I usually cut all 4 sides off, It really depends on the slab and generation.
As it so happens, I recently bought myself a portaband, billed to a prior job. I'll keep that in mind for whenever I feel the need to free a coin from it's coffin. Thanks!
There is a short video on here from @lordmarcovan showing the easiest way to get that done. Prop the holder between a space on a wooden walk and simply step on it. Perhaps @lordmarcovan can post a link to that.
The only way you could screw it up is if you used your bare foot and got plastic shrapnel in your toe. It’s primitive but simple. No tools needed.
While that is certainly an interesting technique, I don't have o wooden porch, and I would be amazed if I managed to do that without causing any damage to the coin...
I’ve done it between a door and the doorframe. Your chances of damaging a coin are actually less with my method than with most tool-using methods (saws, chisels, etc.)
No, sorry. Basically, the idea is to bend the slab until it cracks. It doesn’t matter so much how you do it, or what you use as a fulcrum. You snap off the top part of the slab, where the label is.
