Oldest tin? John Cotton's 1 & 2 Medium, from the 1970s. Other than that, three tins of John Cotton's Smyrna and about a dozen tins of Balkan Sobranie (white label) that date from no more recent than 1981, a few Dunhills from the same period, and half a dozen tins of State Express.
Plus a few pounds of Drucquer & Sons.
Three tins of Dunhill Nightcap, from the late nineties.
Everything else is no older than 2003. But I bought A LOT since 2003.
I kinda started going ape to make up for lost time.
And disappearing tobacco opportunity.
By the way, I bought my first pipe when I was thirteen (in 1972), acquired my first tin of tobacco when I was fourteen (several weeks later). At that time it seemed rather silly to have an elegant and evocative piece of wood..........
with nothing to put in it.
