 abstract = {This paper seeks to find an answer to the question: "How many
stamps are still around, given that we know their prices at issue,
the current price and the amount then issued?" For this purpose, I
develop a simple statistical model, the parameters of which are
estimated for over 1000 postwar Dutch stamps. One finding is that
some stamps are very scarce, that is, less than 100 copies must be
around.},
