The FED has been doing this for years with currency. As a matter of fact, back in the '80's over a long holiday weekend one of their workers took $1 million dollars exactly, and because of the amount the FED lost days in solving this crime because they had to double check all of their paperwork to ensure that their pre-holiday count was accurate and that they were indeed missing exactly $1,000,000. It took them time to do this, but eventually they did resolve their "bookkeeping" problems and did recover their loss.
This is what brought out that they weighed currency and coin.
