Welcome to "The Antique Gambler". One must wonder what an antique is or is not,
the answer is not easy. When it comes to automobiles then you would say that
any  automobile over 25 years of age could be considered antique, though most of
us would still say that it is much older than that time period. US Customs states that
to be qualified as an antique it must be over 100 years old.

Certainly there are old slot machines or games of chance that qualify under the
US Custom rules and many more that are fast approaching this age 

For our purposes we define an antique slot machine as being one that was made 
prior to 1964 and is fully mechanical, though some do have wiring for lights and or
jackpot bells.
