1936s BuffNGC MS67* auction - all legit?

This is a stunning coin to say the least. Currently bid about 2-1/2X what a normal MS67 is bid for on Blue Sheet.
What bothers me a little bit is that Harbor Coin (not shy about puffing their coins) had helped bid this one up. HC and the seller are both in Illinois. Just coincidence?

Any buff experts have comments on this??

That is a breathtaking buffalo! But I'm sure you know what it's worth to you. Good luck. As for the connection, I wouldn't hazard a guess.

The price doesn't seem outlandish to me, just odd about the coincidental Illinois connection.
