I am confused about the clue to philately. Surely the 16th letter of the Greek alphabet is pi, whereas phi is the 21st. What does'scratch in' mean?

You're right Kettledrum, Pi is the 16th letter of the greek alphabet.
"Scratch in" must refer to the "h" being placed in between the "p" and the "i". Recently is obviously lately. Maybe the "scratch in" is "a itch" or "aitch (H)" or is that stretching it a bit.

Trevilino - your guess is as good as mine. Seems a very convoluted way of clueing 'phi'......why couldn't they have said 21st letter?!
