Compound And Complex Errors

Compound and Complex Errors

This section is dedicated to errors that just do not fit into one category because of their compound nature or complexity. You will also find error coins that are of a spectacular or very unusual nature.

This 2.5 gram
Canadian cent was struck sometime between 1982 and 1996. On the
reverse face (struck by the hammer die) we see a dramatic tilted die error
(vertical misalignment). Strong machine doubling affects the die-struck
maple leaf. The die tilt may reflect a loose die, a loose die assembly,
or a die neck or die shaft that snapped in two.

The obverse
face (struck by the anvil die) features three or more overlapping
brockages of the reverse design.

This undated
dime shown above has a 50% cud. The die fragment, while broad, was evidently rather
thin. We know this because two shards of the broken die became trapped
between the roof of the void left in the die and the planchet represented by
this dime. Each fragment left an indentation in the cud and generated
enough resistance for small areas of die-struck design to appear within the
large pucker on the reverse face.
