"big auction site and saw a range of prices."
One of the most interesting things about a Camillus (and Schrade) in like new condition: the wide range of prices people are willing to offer and accept for them.
While Vit is correct with his $60 - $80 range, I've bought the exact same knife, on more than one occasion, for somewhat less and sold same for somewhat more.
Patience is a virtue.
