It likely cost less because of the poor listing and photograph.  I keep my collectible knives listed in a word format, broken down into categories (Barlow, hunter, etc. ) It can save you from getting duplicates.  You can list more info such as how much you paid, who you got it from. year of purchase.  I even mark the knives with paper tags. You can use Microsoft Publisher later to add photos to your listings. Good knife to bargain for a partial payment at a show.Love Bucks!

Congrats on your addition  to the collection!!  Yes some times you do wind up with Gems because of Bad Photography!  Back in the early days of ebay I got a couple like that. Usually from sellers that were just trying to get rid of a knife for a few extra $$   HOWEVER  You can also wind up with junk if you get too excited about the knife and bid reckless and don't study the pictures very closely.  I also did that but was blessed to be able to return the counterfeit knives and get a refund of my bid.   NOW  I always copy the picture  in the Auction and use my computer to enhance the pictures to determine what I want to bid on the knife.  Their are Some knives I don't mind having Duplicates.  I am betting they will go up in value  for those I leave behind.
