I have an ANACS graded coin I received from @Penny Luster and I wanted to open the case... how do I do so?
You have to destroy the case i think like ngc and pcgs an exacto knife would open it just fine without much damage.
You will destroy the case when you free the coin. @lordmarcovan has a video here that I bet you can search. Simple as could be. He placed the holder between the cracks on his deck and stepped on the case. Easy as pie.
It's already damaged... it's been polished, and has environmental damage... that's why I wanted it out of the case
Aside from hitting it you can also just snap the label part off with your hands and pull it out. Or look on the back, there's a seem there and if you get any separation that you can just pull the back off
