The crack on the bell is the result of a series of hairline cracks, likely the result of foundry workers using inferior metals in the construction process
Liberty Bell and Independence Hall (2005)
Issued in 2002, as part of the Greetings From America commemorative stamp series. This stamp includes the Liberty Bell, a prominent landmark in Philadelphia, and a cannon that represents the Civil War and the Battle of Gettysburg.
Backstory and Context
Speaker of the Pennsylvania Assembly Issac Norris first ordered a bell for the bell tower in independence hall and that bell cracked on the first test ring. John Pass and John Stowe, who were two local metal workers, then melted down that bell and created a new one which is what we currently know as the Liberty Bell. A thin crack emerged on the bell and though the first crack wasn't recorded it was estimated to be around 1840 after 90 years of use. Metal workers tried to fix the crack by widening it to ensure that it didn't crack any further, but they were unsuccessful and a second crack emerged going up the bell, silencing it forever.
The bell weighs over 2000 pounds and is over 13 feet in circumference. It was originally used to call lawmakers to there meetings and townspeople to hear the reading of the news. It wasn’t until almost 80 years later that bell began to become a symbol of liberty. The bell also tolled for many special events during the late colonial era and may have been one of the many bells that tolled in commemoration of the reading of the Declaration of Independence. It also probably helped spread the news of the Battle of Lexington & Concord in 1775. By 1772, nearby residents petitioned the government, asking them to stop tolling the bell so often.
Every year on the 4th of July, descendants of the signers of the Declaration of independence have the opportunity to tap the bell thirteen times, symbolizing the freedom of the thirteen colonies.
