Stack's Baltimore interesting tidbit (MPL related)

lusterlover

There is a complete MPL collection for sale as a lot (minus the VDB). If you read the story at the bottom, the seller purchased the collection from Superior in 1974 under the assumption that the VDB was a MPL. It has since graded MS63. I find this quite interesting. Anyone else?

Let it be known to all that I know nothing about MPL's. That being said, I do find myself liking them, a lot.
Looking at your registry, I find myself looking at the pictures and wondering why they look so clean, but grade 65/66/67 with the single 64.
I'm guessing the 64 came as a result of the spot on the reverse. But the pictures fail to show me why the rest grade no higher than they do.
In other words, what am I not seeing?
Thanks in advance for your reply.
Now that being said... I think I would be cracking me some mats out, you know what I mean. If only one went up a grade, would be worth it ... no?
