Whatever happened to the numbers racket?


Now you know why the DJIA is reported to only two digits.

It was originally 3, but made the racket real easy to play - they needed another 3-digit bit of trivia which anyone could easily verify.

And the most interesting cite from that thread:
Relics of the Bygone (and the Illegal)

My father told me several times that as a kid he would run errands for some guys running a numbers racket in Baltimore.
