hi ya Brody - I am not some expert, but I have been around blades.
It looks like your blade might be possibly be a japanise WWII blade. Not one of the cheap NCO blades, but one of the first officer blades that were issued. I say that because you have leather on the suka (scabbard) which is a possible clue.
NOW... many officers used "family" swords, meaning that they swapped out the handles and such for military uniformity, but the blade itself was rather old.
Just looking at the picts you posted on facebook it looks like your blade has a "hamon" or clay markings where they hardened the sword. It might also be a folded steel blade. I think I see some crystalization in the metal, but it is hard to say. This is another clue.
I own a few old swords and have done some research on them. This is why I say that you might have an early WWII officer's sword.
If you are looking to maintain the value, don't clean it or anything. A good place to take it would be a local gun show. There are usually sword dealers there that might be able to tell you more. IF you can take of off the tsuka (handle) the sword should have markings. Those markings could tell you a lot.
Hope this helps.
