Mike,
If it happens to be a milita sword, it's possible you found David Lewis's sword. He was a stage coach robber and served in the military, but ran away from the service and served jail time for numerous acts. He was known to be in the area of Snow Shoe and areas surrounding from records at the Centre County Historical Library. If you need any further info, in the case it turns out to be dated to early 1800's and from the militia, send me e-mail. Good luck!! What a great find!!!
