The result was delete , and I say that with sadness as I used to be a keen stamp collector. The policy-based delete argument is essentially that there are no sources discussing such stamps as a group, which is needed to meet GNG. I am rejecting the argument that the page should be deleted because it is unsourced; per WP:NEXIST, I fully accept the claims that the entries can easily be sourced from catalogues. However, this does not amount to a policy-based argument for keeping. Stamp catalogues do not organise their entries in this way as far as I remember, let alone discuss people as a group. The comments from several participants that research is needed (that is WP:OR) to pick out the relevant entries suggests that this is indeed the case. Stanley Gibbons, for instance, organises first by country, then by year, and then by face value. SpinningSpark 20:01, 8 July 2022 (UTC)
