HOW COINS ARE
There are six stages in the production of US Mint coins. Every
coin is blanked, annealed, upset, struck, inspected, and finally,
counted and bagged.
Step 1: Blanking: The
US Mint buys strips of
metal that are approximately 13 inches wide and 1,500 feet long to
manufacture the nickel, dime, quarter, half-dollar, and dollar
coins. The strips come rolled in a coil. Each coil is fed through a
blanking press that punches out round discs called blanks. The
leftover strip, called webbing, is shredded and recycled. To
manufacture pennies, the Mint buys ready made planchets after
supplying fabricators with copper and zinc.
Step 2: Annealing, Washing and Drying: The blanks are heated
in an annealing furnace to soften them and then run through a washer
Step 3: Upsetting: The blanks go through an upsetting mill
that raises a rim around their edges and turns the blanks into
Step 4: Striking: The planchets go to the coining press where
they are stamped with the designs and inscriptions that make them
genuine United States legal tender coins.
Step 5: Inspection: A press operator uses a magnifying glass
to spot check each batch of new coins.
Step 6: Counting and Bagging: An automatic counting machine
counts the coins and drops them into bags. The bags are sealed,
loaded on pallets, and taken by forklifts to be stored. New coins
are shipped by truck to Federal Reserve Banks. From there, the
coins go to your local bank.
