That's a great website. Facit and AFA catalogues both list quantities printed so I can get an idea for my Denmark collection, but it's nice to have this info available for other countries. When I see that I have a stamp that was issued in relatively small numbers, such as some of the Danish postal ferry stamps, I think to myself that that's the maximum number of collections in the world that could possibly include that stamp, and makes me think that my collection is a little more special
