PART V. Planchet Errors:

Wrong Planchet and Off-Metal Errors:

Foreign Denomination struck on a U. S. planchet.

Definition: Through most of its history the U.S. Mint has struck coins for other countries.  Occasionally a domestic planchet would pass through a coinage press striking coins for another country.

Foreign denominations can also be struck on domestic planchets when a foreign mint has been contracted to supply planchets to the U.S. Mint.  Canada has occasionally supplied nickel planchets to the U.S. Mint and so we sometimes find Canadian coins struck on these nickel planchets.

The 1970 Philippines 25 sentimos shown above was struck in the U.S. Mint on a domestic cent planchet.  In 1970 the Denver and San Francisco Mints each struck 20 million 25 sentimos coins for the Philippines government.

The 1972 Philippines 1 Peso shown above was struck in the U.S. Mint on a domestic clad 50 cent planchet.  In 1972 the Denver Mint struck just under 122 million, 1 Peso coins for the Philippines government.

In 2000 the Royal Canadian Mint supplied the U.S. Mint with nickel planchets.  One of these planchets, shown here, passed through a press striking the January, 2000 Canadian Millennium-series quarter dollar.
