It could very well be a proof, but you have to be careful. The mint that struck these also struck quite a few 'specimen' pieces for their own records, which were sold off when the mint closed a few years ago.
Even so, coins that allegedly show up are often reported as 'specimen' coins and they need to be examined by an expert who has acquired the knowledge in these.
I know some of the background behind these, but unforftunately, I don't know enough to identify the circulation strikes from the specimens.
