So I decided to calculate how much breath is worth.
Jewels said that her Breath got her family enough money to feed them for a year. Her family was composed of herself, her parents, and her five siblings, which totaled to eight people. What lasts eight people for one year, should last one person eight years, as finding the average cost of food for one person is significantly easier.
Assuming they were frugal and didn't eat extravigently that works out to roughly $39,000 USD per Breath. (Based on the average amount of money spent on food by the lowest quartile in 2021, which was $4,875)
Assuming they kept their standard of living as middle class(With roughly $7,600 per year in 2021) then a Breath is valued at $60,800 USD.
Now the real numbers would likely be quite a bit higher, as food used to cost more, however sources from those times aren't exactly giving me the data neccesary.
And just for fun I decided to calculate how much Susebron's trove of Breath is, which worked out to between 24.375 Million USD, and 3.04 Billion USD.
