Penny Project By Aanjan Sikal
Introduction • This project is about numbers , graphs and tallies • I have collected one-hundred pennies and I made a tally chart of the years they were minted. • I also made a bar graph. • I am thanking Mrs. Hood for letting me do this project.
Life of Penny • My oldest penny is from 1953 - nineteen-fifty-three • Did you know in 1953 when this penny was minted • There was no Cell phones, PSP’s, DS’s, Laptops, Personal Computers, Color TV’s or Woodward North (not main campus) • This penny has been around for 56 years!! • Probably even before our parents were born
Tricks in finding old Pennies • To find old pennies I looked for pennies that were • Beaten up • Dark in color • Older pennies change color because they are mainly made of copper • Freshly formed, copper is a beautiful rosy-pink color. • Before long, however, it changes to a dark brown. • Under certain circumstances, it may turn red, black or blue-green.
What is penny made up of • Pure copper from 1793 to 1837. • From 1837 to 1857 The penny was made of Bronze (95 percent copper, 5 percent tin and zinc) • Between 1857 and 1864 the cent was 88 percent copper and 12 percent nickel, giving the coin a whitish appearance. • Again from 1864 to 1962 it was made of Bronze • In 1943 – penny was changed to zinc-coated steel as copper was in short supply due to world war II. They made a few limited copper pennies which are considered very rare and is a collectable. • In 1962, the cent's tin content, which was quite small, was removed. 95 percent copper and 5 percent zinc. • From 1982 it was changed to 97.5 percent zinc and 2.5 percent copper (copper-plated zinc).
About The Penny • Abraham Lincoln has been on penny since 1909 • 1909 was the 100th anniversary of Lincoln’s birth • First US coin to bear a president’s image • Lincoln faces right on the penny • All other presidents face to the left • Because the penny designer Victor D Brenner choose to have Lincoln face to the left
