Welcome!!!
Also, I've seen lists of what the original prices were of Busse Combat knives. I think I've seen a swamp rat list too. I have not seen a scrapyard knife list beyond the photo album of past offerings on the scrapyard website.
Original price can at least give you an idea of what it originally cost someone to buy.
