De-slabbing coins - describe methods here.
« on: September 25, 2013, 05:40:30 pm »
With apologies to Michelangelo:

I saw an angel in the slab and hammered until I set her free.

Setting this coin free was surprisingly easy.  I stood it on its end, put a regular head screwdriver in the groove at the top, and gave the screwdriver handle a few controlled, but firm, whacks with a hammer.  Once the plastic weld started to to crack, separating the front and the back, I worked the screwdriver around the edge of the slab, twisting it slightly to pry the pieces apart.  Took less than 3 minutes.

This time with apologies to Lynyrd Skynyrd:

But if I stayed in this slab, girl,
Things just couldn't be the same.
'Cause I'm as free as a bird now,
And this bird you can not change, oh, oh, oh, oh.

Ha!  I almost used that quote, but I was afraid to go there!

Happily, I've liberated a slabbed coin from its case, with no damage to the coin or myself. This was my first slabbed coin and my first effort to crack one open. It was easier than I expected, taking less than one minute. My confidence was bolstered by posts like this one (a little old, but still useful).

I've learned that there are some differences in cases among the grading firms, potentially calling for different techniques. My case was from NGC, and looked remarkably like the one that initiated this discussion thread.  Hammering lightly around the edges works for NGC slabs.  No special tools are required.  All I needed was a conventional hammer, the anvil (in my case, a bench vise with anvil), and a flat-head screwdriver. The coin case was wrapped in a thin dishtowel, and light hammer blows applied on all four sides. It opened like a clamshell. The coin was then popped out of its foam insert and placed in a ready coin flip, along with the paper tag. 

If I had one of the harder, and more brittle cases, I'd have used tile nippers (plan B: bolt cutters) to bite through the sides closest to the coin.

From your description and picture, it sounds like you had one of the older style NGC slabs.  They are/were much simpler to open than the new style

The old style was basically two pieces placed together and then sealed down the side edge.  Break the seal at a few places, and it popped open, or at least was easy to pry apart.

The new style appears to be a top piece which now fits down inside a raised rim of the bottom.  So just tapping around the edges may not work, or requires a more "aggressive" level on hammering.  I personally use a piers to grab the small lip and bend it down until it pops off.  Do that around enough of the perimeter until you can safely access the coin.

Again, that's my process, your mileage may vary.

Nice work+++  With my one de-slabbing job behind me, I am confident I can do this again, and am now willing to buy slabbed coins. They won’t be slabbed for long  ;).

I was a nervous wreck deslabbing my first two, thinking I was doing something horrible as well as worried about coin damage. It was so easy in retrospect and mine were more recent "tamper resistant" slabs. I think it is clear that slabbing is done to increase prices and give legitimacy to a coin, so I look at that, too. But, now I at least consider buying slabbed coins if the price is right. I do keep the little tags that comes with them.

Yes, that’s the method I use to remove coins from their sealed plastic slabs.

I have de-slabbed quite a few coins now and my method is simple and does not require hammering (which always worried me). I just slowly push a screwdriver into the side crack and twist. One or two spots does the trick. And, to continue the quote theme, from Kris Kristofferson via Janis Joplin:

"Freedom is just another word for losing the slab case."
