Geez, Biokemist, I hope you are wrong!

I bought this coin at a show after getting a second opinion from a dealer that I consider to be knowledgable. He confirmed it as a proof and I remember him pointing out the squared rims. Under a scope the rims are indeed sharp and square. I also notice that the fields are deeply basined around the devices and slope up to meet the rim.
I was hoping to learn some sure-fire way to detect matte proofs, but maybe there is no such thing!
This is another coin that I want to get into a PCGS slab. Hopefully PCI and my dealer friend attributed it correctly, but I'll be a lot more confident if PCGS backs them up!
