In the US there's a "fight for 15" movement happening, where some people are protesting for a $15/hr minimum wage.
In 1964, the minimum wage in the US was $1.25, or 5 quarters:
Today, that $1.25 is worth $15.84. But, you need the same quarters.
$15.84 is the silver value in the quarters you were paid in '64. You don't need a higher wage, what you need is sound money.
