Is this because the stamps are officially honored, or because they just
slip by?  US stamps are phosphor "tagged" so they glow green under short-wave
UV.  I think it is short wave --- the wavelength used to erase EPROMs,
anyway.  In the US, most letters go through high-speed "facer-cancellers"
which look for the green glow.  Letters without a glowing spot are kicked
out for manual handling.  There is also a human operator, who is supposed
to check for the correct rate as the letters go by, but they are, after
all, human.

Are UK stamps tagged, also?  I think they are, but I only collect US, and
don't follow the rest of the world too much.

Are we getting somewhat afield of the purpose of this newsgroup?  Probably.
