When Granpa was my age, it cost only 3¢ to mail a letter. When the letter Georgie found in his basement was originally mailed in the 1950s, it cost 4¢. Now mailing a one-ounce letter costs 49¢.
In Cheesie Mack Is Not a Genius or Anything, I wrote:
I wonder what it will cost to mail a letter fifty years from now…Maybe when I get enough guesses, I’ll put them into some kind of Internet time capsule, and fifty years in the future, if someone finds it, they’ll be able to see how close we were.
This page is as close to an “Internet time capsule” as I know how to build, so at the bottom of this page, you can make a guess.
Here’s a chart showing how the cost of mailing a letter has changed for almost the last 100 years.
