This phrase can be heard at the tables for different casino games, at the poker tournament and at the bookmaker's office.
Dime bet – a bet size of ten cents or one thousand dollars.
The word dime means a dime coin, so the expression dime bet often refers to just such a sum at stake in gambling.
But in the slang of the players, this phrase is often used when we are talking about a rate of one thousand dollars.
Accordingly, to understand what amount is meant, it is necessary to take into account the circumstances in which the expression dime bet sounded.
