Another core coining technology collectors should be aware of is the portrait lathe. Len Augsburger's column in the May 2013 issue of the E-Gobrecht describes an interesting pattern coin which exhibits evidence of portrait lathe markings: a Liberty Seated Cent.

A Liberty Seated cent?
Yes, Virginia, there is
such a thing. In 1853, the
Mint got the idea that different
compositions might
be used for large cents,
and that perhaps the large, heavy coppers could be
replaced with something more manageable. The
Mint began experimenting with German silver, a
combination of copper, nickel, and zinc. The alloy
has a passable resemblance to silver, but in reality
contains no silver at all. Pattern cents were produced
in 1853 and 1854 with varying percentages of
copper, nickel and zinc. The 1854 edition is the one
of interest to Liberty Seated collectors. The obverse
for this pattern was created by reducing an 1854
seated dollar via portrait lathe.
The portrait lathe traced the 1854 dollar
with a stylus moving in a circular fashion around the
coin. This design was then transferred onto the pattern
cent die, with the circular lathe lines imparted
as well. In practice, the lathe lines would be polished
out on the die, leaving no trace of the reproduction.
In this particular case, the Mint was more
interested in trying out different alloys, and in haste
neglected the polishing. Even on modern coinage,
lathe lines are sometimes seen - I have a 1996-D
Lincoln cent pulled out of circulation which demonstrates
the effect, although to be sure it is much less
pronounced than on the 1854 cent pattern.
Among
Liberty Seated coinage, the Scott Confederate half
dollar restrikes (executed in 1879 using 1861 half
dollars) frequently come with evidence of lathe
lines, although this is thought to have occurred
when Scott ground off the reverses of the coins before
restriking them with his own reverse (which
was a reproduction of the Confederate half dollar).
Back to the 1854 cent, these of course never
caught on, and the Mint decided that a smaller format
piece in copper would work just as well, and so
the 1856 flying eagle cents were born shortly thereafter.
To be sure, the coinage was debased, with a
smaller amount of metal representing the same face
value - governments are good at such things - the
Liberty Seated silver coinage, in 1853, had of course
also been reduced in weight. Nevertheless, the German
silver experiments of 1853 and 1854 leave us
with a curiosity in the Liberty Seated series, a coin
that tells a story about the technical production of the
Mint in mid-19th century.
The E-Gobrecht is the electronic newsletter of the Liberty Seated Collectors Club, and the May 2013 issue is #100! Congratulations! And here's a larger image of the coin, where the circular markings are readily apparent.
