But that was $20 back when the Constitution was written. Adjusted for inflation [1] and you could be looking at anywhere from $390 (CPI) to $941,000 (relative share of GDP). I have no idea how that is applied today.
I don't see where it says "corrected for inflation" in the Constitution. If the government wants to, by policy, devalue the dollar and make it easier to claim jury rights in civil cases, that is its own fault.
