Welcome to
Tim
Steve is right about finding value in the current market through eBay
and mint and original sheath will get more than it being an older variety
but some collectors might pay more if they know what they are looking for and some might not
Pics of it would help and we all love pics here anyways
Also is it stamped US Pat Pend on both sides
I have one that is stamped with US Pat Pend on one side and the other has US Pat and the number
Still an oldie either way and neat to have
