That's a Sacagewea dollar coin! Let's talk to a mine worker to learn more!
The dollar coin is made of Manganese-Brass. It has 88.5% copper, 6% zinc, 3.5% manganese, and 2% nickel. Our copper mine is located in Arizona, but the other parts of the metal are mined in China, South Africa, and Russia. We extract the elements in an open pit in the ground with heavy machinery. On the periodic table they are located in the middle with metals. Now that you know a little more about what the coin is made of, go talk to Glenna Goodacre about her coin design!
The United States suggested in 1998 that the $1 coin have the face of Sacagawea from the Shoshone Tribe and who guided Lewis and Clark on their famous expedition. I used RandyL'He dow Teton of the modern Shoshone tribe as my model to get the most realistic design, Out of 23 artists, my design was chosen in 2000. Now, go check out the U.S. Mint to learn more!
This United States Mint is located In Philadelphia, Pennsylvania. Many more exist in Denver, San Francisco, and West Point, New York. The coins are $1 in value and last for 30 years on average! We make new coins by melting the metal down into a circle. Then, we use a metal stamping machine to press the new design into the coin. We recycle these coins by melting them back down to use in other coins. Now, go back to your classroom!
And we can do more fun activities about coins in class!
Wow! I learned so much about the $1 Sacagawea coin!
