My latest Papuan Pandemic Project is an attempt to value my stamp & especially cover collection. My Vern Rutherford, Roger Lee & Powell postal history books give some clues based on PO opening durations but no one appears to attempt a scarcity rating or valuation for town & special cancellations. Are there more recent references that might help?

Vern draws attention to Issue #72 of PPS Stamp News dated December 1964 but I have not been able to find it. In any case that is not exactly recent!  Another option is to wade through auction prices realized but where to start?

I’d be grateful for any suggestions.
