A classmate of mine that is working at Main State sent out an email that he saw people using the seal and stopped to look in, only to see a commission for one of our A-100 classmates. So we knew these were coming, but it was still very cool. When I went to pick up mine, the folks in personnel said congratulations. I worried I would drop it on the Metro tracks or have it blow out of my hands on the way home. I managed to make it home without incident.
President Obama and Secretary Clinton's autopens signed the thing, and speaking as a nerd I have to say I find it very cool. I don't think either of them know that they have placed "...special trust in my Integrity, Prudence, and Ability..." but it's pretty neat having a piece of parchment that says so.
Seeing it helps put things like months more of language training in perspective, as I can see where the tedium today is a means to be able to act as a Consular Officer and Secretary in the Diplomatic Service in Jakarta next year.
