I don't agree. I don't believe that pipes are a good investment. There are exceptions. Certain Danish makers, patent numbered Dunhills, Magnum Dunhill's etc, as well as some artisan pipes like Butera, can bring you a good bit more than you paid for them, but most pipes will loose too much value over the years.
It seems to me that some old time collectors are turning loose their Dunhill's, Charatans, Comoy's, Barlings, and Sasieni's to put their money into new Danish pipes such as Chonowitsch, Bang and older Iversson's and Nordh.
These seem to be the hot thing at present. But when collectors were buying the old English pipes and setting them aside for future profit, they were the hottest thing.
If you look on Ebay, and other pipe for sale sites, pipes are not fetching very high prices. I picked up 6 high grade Charatans last year from private collectors for hundreds of dollars each, when I'm sure at one time they were bringing many times that. Two were unsmoked. I think that they are worth what I paid for them, but not worth what I used to see them go for.
I have yet to purchase a Chonowitsch or a Knudsen pipe because I refuse to pay collector prices for something that I can get in older high grade English or Italian pipes, that are no longer the hottest thing. Excellent workmanship using the best materials available at the time.
Of course the Chonowitsch, Knudsen and Eltang are artisan pipes, and not a factory made, but come on. It's a pipe or Christ sakes. Meant to be smoked, not put away in a safe just so you feel smug, and bragg about what you own. And when these are no longer the hottest thing? What? Try to sell them off just to go after what is at the time?
There are some Russian makers that are attracting a lot of collector interest at present.
I guess you didn't want to hear this rant, but it's a sore topic with me. How much is too much to pay for something that is supposedly made to bring you pleassure by smoking it? I don't know. But I for one refuse to play the game. At least where pipes are concerned.
I say buy what pipes you like, but at least smoke them. Don't buy a pipe like you would a piece of jewelery to put in a safe and hope it appreciates.
