Founding Fathers believed in hard currency, so how much would the weight of two $10 gold pieces be worth today? In 1933 or thereabouts after Roosevelt took all the gold in at $20 and then devalued it to $35 and ounce might be a starting point. I'm guessing an ounce of gold just before the depression, so maybe it was 2 ounces in our Founding Father's day. Today that would be about $900-950 depending if you are talking just gold by weight.
as the text of the 7th amendment reads;
In Suits at common law, where the value in controversy shall exceed twenty dollars, the right of trial by jury shall be preserved, and no fact tried by a jury, shall be otherwise re-examined in any Court of the United States, than according to the rules of the common law.
I guess $20.01 was worth a fight back then. I just found the mention of a specific amount to be interesting amid other talk about constitutional relevance and interpretation.
