Some tin old

George had been curious about the old baccy tin (crammed with a very miscellaneous bunch of badges). 

First, he couldn't get his head round the fact his grandad had, at one time, smoked.  Then, he couldn't get his head round the fact that when I was a kid I'd often get sent to the local shop for some Old Holborn. 

He seemed to get the idea of "you can keep the change for going" easily enough though.
