From http://www.dollartimes.com/calculators/inflation.htm ,
$1.00 in 1937 had about the same buying power as $15.02 in 2009.
$1,200 x $15.02 = $18,02400.
Benny’s $10,000 fine was $150,200.00
(Note: inflation calculator web site formulas can vary.)
wow, thats steep.
And for perspective, the jewelry was worth more than a Cadillac.
