I've heard it argued that a year stamp would affect the value of pipes not sold during that year, make them look like old inventory. To the contrary, in a field where age is generally looked as an attribute, I think that prejudice could quickly be educated out of the consumer base. An older pipe, unsmoked, in prime shape, can only be said to have more aged briar and therefore be more valuable, or at the very least as valuable. I'd love to have a birth year Savinelli, Genod, BC, etc. But I'd be dubious without a stamp to prove it. I'd figure someone was just pulling my chain. And since they've never been stamped, I'd know a year stamp or a code was a clever addition. Hey, I happen to have a stamped birth year pipe; just let me go in the back for a minute. No Dunhill, no birth year, no thanks. I am glad to know Castello has gotten aboard for younger people.
