1832 Bust Half Meyer Collection question(*pics posted!)

I have started a type set of bust halves in PCGS slabs. However, the two I've come across both say genuine with the Meyer collection attribute on them. The code 6160.GN isn't a cleaned code, so I was wondering if anyone knows the story behind these particular halves. I have an 1832 SL bust half that is definitely BU to my eye.

There was once a 1943 copper cent in one of these holders, with a deep scratch on the obverse where someone tested to see if it was plated (should have tried a magnet)
Post a picture of the coin, if you can, it sounds like it's nice and has a cool pedigree and historic holder

MS Details
An absolutely beautiful coin!
Knowing where this coin came from, it would not surprise me if this is "special" example of
an otherwise common O-102 (R1) probably a 102a. (R3)
I'd grade it MS net, but it looks like it had a recent dip. Very nice details.
Here is what Overton says about the Reverse:
Arrowheads malformed and solidly joined.
Die defect at tip of right wing.
