I asked for a sheet of national stamps. They gave me prior stamps which do not have “prior” printed on them. Price was high, but I just figured the postage rates are jumping leaps and bounds. It turns out a circled 1 “①” is apparently a priority indicator.

Just a heads-up… watch out for that. The normal stamps come in a sheet of 10 and I think it’s the head of a prime minister on those things.
