1835 Half Cent How To Tell A Proof

Let's start off with this- does anybody know what would constitute a marker for a proof coin. If I understand correctly, the proofs were struck with the regular dies. In 1835, only two varieties are known and it is believed (despite Breen's claims to the contrary) that all proofs are C-2.
I picked up an 1835 Half Cent and it has an interesting look to it. I began to suspect it may be a proof. After looking at lots of pictures online, I found that all known proofs show considerable doubling on the reverse about the one cent. None of circulation strikes that I found had that.
This is not an actual doubled die, but I am theorizing that the multiple strikes of a proof production caused a reduction in the devices. If this were true, which is an if, could it possibly be an indicator of a proof?
Now, I am out of town without access to my proper photography setup, but my patience is less than stellar. I snapped some quick pics with a phone. The dark toning with thr halos about the stars is actually supportive of the proof possibility see the NGC page with the examples.
In summation, I have witnessed many people on this forum get their hopes up and be set straight by the level-headed folks here. It would be quite a find to have stumbled on the 19th example of the 25 original minted, and as they say, extraordinary claims require extraordinary evidence.
Let's hear your thoughts please.
