Liberty Bell
Park Service administration (1948–present)
Today, the Liberty Bell weighs 2,080 pounds (940 kg). Its metal is 70% copper and 25% tin, with the remainder consisting of lead, zinc, arsenic, gold and silver. It hangs from what is believed to be its original yoke, made from American elm. While the crack in the bell appears to end at the abbreviation "Philada" in the last line of the inscription, that is merely the 19th century widened crack that was filed out in the hopes of allowing the bell to continue to ring; a hairline crack, extending through the bell to the inside continues generally right and gradually moving to the top of the bell, through the word "and" in "Pass and Stow," then through the word "the" before the word "Assembly" in the second line of text, and through the letters "rty" in the word "Liberty" in the first line. The crack ends near the attachment with the yoke.
