As Brigham Young University celebrates its sesquicentennial year, a part of that celebration includes looking back and the school opened a time capsule buried in the cornerstone of the Harold B. Lee Library during Thursday’s celebration.

What was inside?

While just 50 years separate today’s students from those who sealed the last time capsule, much has changed. During the unboxing on Thursday morning, BYU noted on X that among the unearthed items was a “crisp $5 bill,” joking that it “stretched a bit further back then.” A tape measure was also included, a potential prediction the U.S. would have switched to the metric system by now.

Another highlight was a recording from BYU alumnus Harvey Fletcher, often called the Father of Stereophonic Sound and the inventor of the first fully functional hearing aid. Fletcher died just a few years after the time capsule was buried in 1981.

The capsule also contained letters from faculty and staff, and even a game-worn jersey from Elder Gifford Nielsen — former BYU quarterback and current General Authority Seventy of The Church of Jesus Christ of Latter-day Saints — and a special Centennial BYU flag that was designed for the 1975 celebration.
