But how far back are they valid for postage? The Wikipedia article
"Postage stamp demonetization" seems to be accurate for the 4 countries
it covers [HK (1997), USA (1861), UK (1971), Poland (1998 or later)] but
what about the rest? Is there a more complete source of this information?

How many countries can we work out between us?

In Belgium it is difficult to draw a line. Basically a stamp is valid
for postage unless it is explicitly mentioned that is not valid. You
would have to buy a Belgian stamp catalog to know. All stamps issued
after 2 October 1961 are valid, but many stamps issued before this date
are also still valid.
