There is actually a whole market for collecting vintage tobacco tins. I have collected several vintage tins and am have been expanding that over time. I love going antique shopping and tobacco tins are at the top of my list for items to hunt for. Like most markets, condition and rarity determine price. Also, as in all markets, there is a big difference between reasonable pricing and just plain ridiculous. I am willing to pay a few bucks but am not about go broke no matter how rare the tin.
As for current production tins being collectible...if it happens it won't happen until maybe your grandkids are in the hobby. Most collectible tins are from the 60s and earlier with the older and rarer tins being the most valuable.
As technology and legislation has evolved it really has changed the market for what is collectible. Paper products don't really last and different tax laws hinders distributions.
Also, the tins that are the most collectible are the tins from brands that are no longer around or were not main stream. Velvet is no longer around (I think) but there we pretty main stream so their tins aren't very valuable. Half & Half and Prince Albert are still available and were what most people smoked, so other then nostalgia there isn't much value there either.
I think just as with pipes, it is really a matter of what you like. I too like all three of the seasonal Peterson blends and half order them for the tin as I do for the tobacco.
