When I bought a P-15 note off a dealer a while back it just had "Exceptional Paper Quality," no "Stamp Cancelled" designation.
So I was surprised when I submitted my 12 traveller's checks and all 12 got the label.
The new P-17 I just got, which has a cert# indicating it was submitted after mine were submitted and graded, does not have the designation.
So, I'm really not sure what this means... I'm not sure if they just forgot to include it on this one (which I think was one of 4 or 5 the seller submitted with this group) or if they aren't sure if they're going to keep using it or not, or what.
But this introduces the idea that my 12 are the only ones that have this label / comment and they may stay that way. I wonder if that would make them more or less valuable?
The joys of trying to build registry sets over time and with notes you bought and which were graded by others over a longer span of time.
Side note, but you can really see that Zimbabwe bird watermark (or at least the outline of it) when you look on the back of these things, at least in my scans.
