hello class im here to talk to you guys about the dollar coin!
there is a dollar coin?
i never heard of a dollar coin. what is it?
the Sacagawea dollar coin was made in the year 2000. The designer of the coin is Glenna Goodacre. On the front of the coin is a picture of Sacagawea and her baby and on the back is a picture of a bald eagle in flight. a mold is sculpted and then shrunk down to stamp out the coins
what is it made of?
the coin is made of 88.5% Cu, 6% Zn, 3.5% Mn, 2% Ni. The materials are all transition metals and are mined from within the earth. The minerals are removed from the ore and processed so it is usable. The materials keep the coin strong and durable so it last longer. The dollar coin will last up to 30 years and can be remade into more coins
