I would sympathize with the graders that this one is tough to spot , and likely should not be a variation either in SCD or the Registry, but if PSA is going to include they should have someone on staff that knows what it is or isn't.
To me the blob version is more distinctive and easier to identify. In fact ,even the blue dot by the cap thing posted by Cliff above is more interesting to me
Is that recurring too ?
I like collecting variants but this one is a dud even for me.
