James T. Kirk (William Shatner) with his phaser rifle

A rare phaser rifle used by William Shatner in the second pilot made for 
the original Star Trek series sold recently for $231,000 at an auction
conducted by Julien’s. It is the second-highest paid at auction for a prop
from the 1960s edition of Star Trek, surpassed only by the $304,750 a
collector laid out for the captain’s chair in 2008. In 2006, a miniature
special effects model of the enterprise from Star Trek: The Next
Generation sold for $576,000. 

The phaser prop is made of wood with an aluminum barrel and is painted
with a metallic blue-green paint. The rifle was never appeared in another
episode, though it was seen in publicity photos of Shatner as Kirk and on
an early lunchbox (below).
