First off WELCOME to TFF, pull up a stump and go get your favorite brew, have some waders handy because it gets kind of deep in here sometimes.
As to the 99. There are quite a few different 99's. Which one do you have? I just sold an "A" in 300 Sav. caliber through an online gun auction. It had some flaws in the wood (pieces missing and cracks that were fixed) there was some rust on parts of it, and the front sight had been replaced. It brought $250. Yours sounds like it is better shape than the one I had so it would probably bring more, depending on which one you have.
