Postmasters Provisionals To Expertise Or Not

In a collection I have purchased I found this New York 5 cent Provisional.
It is quit an expensive stamp and I'm considering to have it expertised. But before I start this process I would like to hear from the experts what they think about this stamp ( real, fake or reprint) as far as this can be judged from a scan.
When you consider that it might be a real one I also would appreciate some advice as to which expertizing body I should use.
Thanks for your help

Here is a real stamp
