I've always thought that, on long trials, jurors should be paid a wage equal to a court bailiff.
I have an alternative idea. Since the U.S. Constitution contains this:
Section 10. No state shall ... make anything but gold and silver coin a tender in payment of debts; ...
I'll take one or two of these... $5 Gold Eagle. They'd still only be paying me $10/day, but that's OK, since it's actual money.
