U.S. stamps are heading for their sixth price hike since 2021. In raw numbers, only four countries in a recent study of 31 developed nations had cheaper stamps than the U.S.

The stamps honor the Snake Island soldiers who answered a Russian calls to surrender with "Russian warship, go f*** yourself!" Ukraine's postal service had to limit purchases to six stamps apiece.

The most valuable stamp in the world, the British Guiana One-Cent Black on Magenta, failed to set yet another world record at auction.
