"It is made of Cast Iron....it works on a U.S. Penny! It is called
a 'Penny Music' (no manufacturer name anywhere on the wallbox).....it
is a 'Penny Drop', meaning the penny drops thru several nail heads,
(you can watch the penny thru the front glass as it drops) and if it
falls into the center (where the Arrow is) it would hit a contact
and put a credit on the jukebox....if the penny lands to either side
of the center you just lose your penny (so the 'wallbox' is actually
kind of a 'penny drop' gambling device too!)......."
