The Forever Stamp is forever rising in price. How does the U.S. cost compare globally?

The cost of a Forever postage stamp is poised to rise in July, under a U.S. Postal Service plan to boost the price of the first-class stamp to 73 cents from the current 68 cents — a price that was just raised in January.

The 5-cent increase would take effect on July 14. If it's approved by the Postal Regulatory Commission, it would be the sixth price hike since January 2021.
