Although collectors like HKINGDOM and EEE seem to have about everything, no one can collect all the Buck knives that have been made.
You sort of have to pick your category and fill it in.
I bought my first BUCKS in 1963. That sort of determined the direction of my collection. I have thereafter focused my collection on BUCKS made after the company was incorporated on April 7, 1961 up to 1973. When they started putting the model number on the knives, I decided that I would stop with that year, 1973. Next, I am not a big folder fan for my collection so I have concentrated on the 100 series fixed blades. Of recent years, however, I have slipped out of my categories and added some other quite rare models (even some folders) to the collection. To my amazement, I find that I have about 40 folders but they do not have any significant theme to them. Oh, yeah, then there are the Limited Editions that have sneaked into the group. The bulk of my collection remains the 100 series knives.
As you can see, BUCK collecting is a virus, it just keeps eating at a collector and expanding and expanding and expan.......!!!!
Then there are the 1940 to 1960 Hoyt Buck knives.....mortage your house!!!
Do they go up in value? I was just looking at a 1970 catelog price for a BUCK Frontiersman 124. It was offered for about $35.00. I have seen them sell on EBAY for $350+ dollars. Some less depending upon condition, packaging and papers.
Now 41 years ago, who would have thought that those would go up in price like that. I am not sure that the current BUCK models will accelerate like that since mass production results in many more available on the market. Remember, the first 1967, Teflon spacered 122/124 Nemo/Frontiersman had a total run of 300-500 knives. The Nemo from that period sells for $500 up due, in part to its rarity.
Some BUCK knives didn't work out so well, so not many were produced. Those, of course, are higher priced. I suggest, only as a couple of examples, the 121 Scaler, the phenolic handled 124 and the BUCK Sawby.
So I didn't answer your question. I have only this advice, once you have determined what appeals to you,
not their investment value, pick a category and stick with it. If you catch the virus, even that determination won't last very long.
