Is there a proper or safe way to do this?

Wrap it in a towel, stand it on it's side on a hard surface, and give it a rap with a hammer 'til it cracks. There's lot's of info on this.

There is no slab which will resist a Dremel.

Seriously, that's how I do it. I cut all 4 sides of the bottom pane which holds the coin, and am then able to just lift off the upper piece to expose the coin. No chance whatsoever of mucking up the coin, as long as you're good with a Dremel. I use the metal cutting disks, and attention must be paid to avoid melting your work back together after you've passed.

I wrap the slab in a towel and put it lengthwise in a vice and slowly turn the handle until I start to hear a nice crack. Usually that does it. Sometimes it takes an extra crank or two on the vise but that seems to work well for me. Once the slab starts to crack I can usually pry it apart and remove the coin without damage.

I've never had a reason to break open a slab, however I have a 2004 S L&C nickel that's graded "PR-70" (yeah right) by SGS. It's more so a PF68 or PF69CAM. Those SGS holders are complete and absolute garbage. Towel + mallet + maybe 2-3 hits = done

I use SuperDave's method, but in a primitive way. I use a handheld can opener, in place of the dremel.

Tin snips here. Less than $10 at the home improvement store. Cuts the slabs like butter, no coin damage. Done it 20 or 30 times.

I recently picked up these at Home Depot for $19.95, and they work very, very well.

I find it's a good idea to cover what I'm doing under a towel to prevent small pieces of plastic to fly in a bad direction.

They only slabs that take a little muscle are the PCGS ones. They are just plain sturdy.
