Odd-looking Large Slab Seam

In most cases, I don't see much of a bondline on the large 5 oz ATB slabs, but I just received one that has what appears to be an uneven bead of solidified plastic along one of the seams of the slab.
I've inspected all sides of the slab and see no evidence of cracking or damage, and the coin itself looks good. However, I have recently returned a 5 oz ATB with obvious evidence of the slab being tampered with.
Here's my question - can a large ATB slab have a bondline with solidified plastic that oozes out of the seam and still be legit?

The sonic sealing machine works by melting the plastic. The slab is specially designed to interlock so that when it hardens there is a solid bond. It could have been not quite perfectly square in the machine.
Contact customer service, they'll reholder it for a nominal fee.

Sonic sealing can leave imperfect seams if the halves are not perfectly aligned...If it bothers you (and since most coin collectors are OCD), then send it in for a new slab. Otherwise, every time you look at it, you will focus on the imperfection. Cheers, RickO
