Any idea as to what my next move is in regards to this coin?

I apologize if replying to my own thread is against the rules, please remove my post and it won't happen again.  Just posting a full pic of said coin for context.

Hello all,

First I would like to say that I greatly appreciate anyone's time who can shine some light on this coin, or pass any information my way.  I have what I believe is a 1925 Belgian Congo 1 Franc (KM #21) that appears to also have an overdate error....is this a 1925/3?  I have spent many hours trying to research this coin, only to find next to nothing in the way of rarity, mintage, etc, even a picture that's similar to mine!  One database informed me that the coin does "exist", lol.  Do I actually have something here, or is this another case of a novice's eyes playing tricks?  In the off chance that it actually is a rare variety and not a smudge on the coin or whatnot, what would be my next step?  What grade would this be considered?  Thank you very much, I look forward to any and all replies! Please advise!  I would be happy to provide more information/pictures upon request.

EDIT: This is my first time here, so please feel free to crack the whip if I've made any mistakes!  Much appreciated :-)
