I hate to jump in here, but the prior posters are correct. If the rifle is really unfired, then it is worth thousands.
Now, I totally understand that when you find a rifle you really love, a part of your mind tells you that you should just shoot it and enjoy it.
But, in this case, you would be doing two very negative things: first, you would be destroying history, and second, you would be destroying lots of value. All lost forever.
May I offer this solution? Go online, and find the really serious Savage 99 collectors. Tell them what you've got. Send them pictures. Go to somebody that they recommend, to have an expert confirm that it is really unfired.
If it is unfired, or even if it is fired and in 99% condition, then you should be able to trade it to a serious collector, and receive in exchange the exact make and model that you have, in 95% to 98% condition, plus a fistful of money. The used rifle you will receive will be used, but not abused, and only slightly worn. You will have the joy of hunting with a rifle that someone used almost 100 years ago. And, you will have the pride of knowing that you preserved a pristine model, for future generations to look at and enjoy.
Best regards,
