NGC holder with sharp edge sides? 1 1

[The Neophyte Numismatist]

I recently bought a 1939 Proof Nickel.  It's in an NGC EdgeView holder.  This holder scans and matches my coin.  I have no concerns about the coin, it's authenticity, or grade (love the coin).  However, the seam along the sides of the coin is sharp to the touch (where it clamshells together).  I have a good mix of PGCS and NGC slabs, and I have not had one that is quite this pronounced. This is not something that I can easily photograph, but it can be easily felt.

Anyone else have a "sharp slab"?

I have seen a few. It seems like it happens is they “over bake” them in the sealer maybe. But yes it does happen.

Appreciate it.  I will have to pay more attention now out at shows.

Yep, they can have sharper edges than normal. As Woods said, they were probably over zealous with the ultrasonic sealer, had it set wrong, tooling was worn, etc..

yes some of my latest slabs have the plastic built up around the seam.  this does create a little sharp pieces around that seam.... got a batch in the hopper right now i will let you know.

Hmmm....I thought they used an E-Z-Bake for this. The things ya' learn when not paying attention!

That's the winter slab; it provides better grip in slick conditions...
