Lol I usually like the look of the holder myself, but the grade was actually lowering the value of the coin from raw and those coins look much better than the grade they gave them. So they will stay with me in their mint boxes Report this Post to the Staff

I only have one and was surprised to see they can't be opened. I understand why now that I have learned a bit about certifications, BUT I am also surprised no one yet (that I have seen) has mentioned HOW these things are sealed by the certifying company. My guess is they use ultrasonic welding. These companies will regrade coins for people which means they also need to open those slabs. Somehow I don't think they use hatchets on multi-$$$ coins...

silverwolf Pillar of the Community Canada 3733 Posts	Posted 11/13/2020 6:27 pm I would believe they use a dremal type tool. and cut off the edges, to open the holder, they don't use vises, or a hammer... Report this Post to the Staff

leftcoastcoins New Member United States 26 Posts	Posted 09/30/2021 07:25 am Depends, If its a high value coin, I take a Dremel precision (jewelers size) torch with a cutting tip and very carefully remove the outermost edge then peel back the sides. If not I take a large pair of lineman's pliers with a cutting edge and snap off a side and go from there. Report this Post to the Staff

OldSilverDollar New Member United States 27 Posts	Posted 09/30/2021 5:56 pm I put the edge of holder in a pair of vise grips while holding it above a small trash can. then I use a a hand shear to trim a little at a time around the case until the middle remains. Report this Post to the Staff
MintPenny Valued Member United States 74 Posts	Posted 01/01/2023 12:15 pm Say what you will about the post with the video cracking open the case with hammer - it is the one I used and worked like a charm. I had a steel phone holder my company had sent as a gift and put the case in there to hold it and used the hammer to give it a good whack on each side and VOILA opened like a charm. So thank you to the new member who posted that video and to the person who made fun of him - just stop-grow up. Report this Post to the Staff
