Well, in some cases it is just the tin, just recently I bought this PJ Carroll tin just for the tin, because it's so rare, they were one of the last great Irish tobacco houses, famous for Mick McQuaid,

...I had never seen that tin before and I reckon it's late production right before they went out of business, I have no concern that the baccy may be too dried out or unsmokeable, but I am curious if it's just a "normal" aro or a cool oddly flavored true Irish stout kind of thing, I hope it still has an aroma!

It was a little pricey, but I could not resist it!
The same seller has a rare Japanese tin still up for grabs,
the Momoyama stuff I've seen sell for big $$$ and this is by the same maker,
12e + 9e shipping = roughly $30, pricey for just a curiosity, but pretty cool...
