I went by a local coin shop to pick up 2 or 3 edgeview slabs only $3.00 each. I noticed 2/3 have that little plastic line below the label raised, and you can't stack them ontop of eachother, because the slab surface isn't perfectly level. Why is this, and is the sealing poorer or what?
I do not have an edge view slab I can compare, sorry. Most of the slabs are designed for convenience of machine sealing, or some preventative such as security or preventing scratches on the faces. Regular PCGS slabs stack Ok, but the faces that match can rub and scratch each other if dust gets on the surface. NGC regular slabs do not stack, but the faces are recessed so they scratch less. Best guess. Jim
I don't think that I have seen the little plastic line on an NGC slab "raised" outside the slab. The plastic line is "raised" inside the slab where it presses into a recess in the internal insert so that the upper paper label is kept somewhat separated from the lower coin location. P.S. Please confirm that these are NGC slabs including coins that you purchased for $3 each.
That's what i meant, the inside plastic line is supposed to be stuck into the groove of the white core, but on my they groove up a little bit, almost like at 170 degree arch/curve, and this causes the surface of the slab to be raised, so it cannot be stacked.
Unless I am misunderstanding you, NGC slabs stack fine with other NGC. Edgeview and older styles. You are correct in that they don't stack with PCGS other than two just two coins with the NGC coin on top, but normal NGC slabs are indeed stack-able. It would be very helpful if the OP were to post photos.
Am I reading this right? You are buying EMPTY NGC slabs? I don't think that's possible but let us know if this is the correct interpretation.
No they are not empty, they have a random coin in them, really only worth face. I'll get pic's later. If you push down on the front of the slab, they stack better, but the line below the label is arched towards the center.
My first though would be to question the authenticity of the slab itself. I just checked all mine and there are no raised lines on the surface of the slab anywhere. Maybe you could check the certification number here > http://www.ngccoin.com/certlookup/index.aspx And as noted, good clear picture would be helpful.
They are legit, i compared them already with NGC's verification when i first got them. Here's a picture. One of the black lines is an example of that line being flat in the white core, but the other one shows how it is arched a little bit out of the white core, more towards the center of the line.

These 2 coins are not mine, but the one on the left has the raised line as i am talking about, the right one does not have the raised line Uploaded with ImageShack.us
What do you mean? I have a edgeview with one, and in that pic is a old fat boy with the same problem.
What do I mean ? They have a lot of different kinds of slabs is what I mean. They are not all the same. Or it could be something as simple as a error in the plastic, from the mold maybe. If you're concerned about it possibly being a fake slab then send it in to NGC. They're the only ones who can tell you for sure.
I'm not concerned of it being fake, because i had this problem on old slabs that got re-slabbed, so obviously they aren't counterfit. It would be nice to know what causes it, maybe the weld pressure when they seal it or something, i dont know.
I'm thinking just sloppy assembly. They didn't get the ridge in the inside of the shell nested down into the groove in the insert, If it isn't seated properly it can cause the shell to bulge at that point, possibly deform the ridge up or down etc.
That's what i thought too. BC most of these slabs that have this problem also have a sloppy label, meaning its curled or not completly flat.
