I got a gold buffalo in an NGC slab today.
When getting ready to log it, I noticed a little tab of plastic about 3mm wide sticking out of the top and bottom of the slab. Using a loupe, I could see some of this inside the slab below the sealing edge. I cannot find another of my NGC slabs that have this.
Is it normal or is there a chance the slab was cracked and a lower grade inserted? Would photos help?
Thanks much,
Seth
