Mis-Struck OverStrikes
The manufacture or remanufacture of large batches of coins did not always go smoothly. At times, the coin being reused was already a mis-struck error. At other times, perfectly good original coins were turned into errors during the Restriking process.
Below are (in order),
an OverStrike with the underlying design Off-Center,
an OverStrike with the top strike (new design) Off Center,
a Double Struck OverStrike,
and a re-used Brockaged planchet.
Sometimes, the original coin was Off-Center

A 1755 Kopek struck over a Cross type 5 Kopek
(Please note that the underlying Cross is Off-Center, lower right)
Sometimes the Over Strike (top strike) is Off Center

An Italy 1918 20 Centisimi struco Off Center over an Italy 1894 20 Centisimi
And sometimes the OverStrike is Double Struck
A French 1704 ½ Ecu Double Struck over a 1691 ½ Ecu (see insets below)
(Please note the original 1691 date in the lower left obverse legend and the two 1704's near the top of the reverse).


At times, old Mis-struck coins were used, as in the case of this OverStrike over a Brockage:

1766 Netherlands East Indies Duit, OverStruck on a Brockage)
(Note the inset "V" and the backwards date on the reverse)
There are many OverStruck coins available, starting at only a few dollars each. A great collection of Overstruck Errors can be made!
