clashed cap strikes -- a primer
- In post no. 1227, I mentioned an error called a "clashed cap
strike". The concept and terminology goes back at least to the
Most clashed caps involve a late-stage die cap with a featureless
reverse. The first strike of such a clashed cap ("clashed cap
strike -- first impression") therefore features a sharp, unexpanded
brockage superimposed over a strong raised ghost of the obverse
Of course, any kind of cap can strike the anvil die.
If a mid-stage obverse die cap strikes the anvil die, then you'll see
a sharp unexpanded brockage superimposed over a stretched out,
If a cap that was striking counterbrockages collides directly with
the anvil die, then you'll see a sharp unexpanded brockage
superimposed over a counterbrockage.
Other possibilities exist beyond these.
For some reason, first impression clashed cap strikes appear to be
much more common than true first-strike brockages. Unfortunately,
these clashed caps are often sold as first-strike brockages.
If anyone wants to see images of these various types of clashed caps,
just let me know and I'll post some.
