The US Coinage standard for government issued coins was set way back in the 1800s. Perhaps walking coin encyclopedic madfranks will nail down the precise year while enhancing this discussion. Mamboni touched upon it in his post above, but it was the coinage act of 1792 which dictated the approximate 90:10 silver to copper ratio. The ratio was actually 1485 parts pure silver to 179 parts copper alloy, which is closer to an 88:12 ratio, which was later modified to the standard 90:10 ratio in 1836.
