"Hoarded" means Bar, Coin, Jewely (ie. shape change) "Consumed" means assimilation into a larger product. I made a mistake with Copper. I mentioned "Strong Consumption" twice. It doesn't change the maths.
Plat price has been battling hard and silver now $26. Not sure the rank good for plat and fair for silver can be uphold
I arbitrarily assigned the simplest number value possible to each possible state in the "Summary of Major Economic Influences". Each following column is maths. "Summary of Major Economic Influences" values added together = 'Effect" column. "Price Stability" is based on "Consumed?" column. 'Worthiness" column = "Effect" column + "Price Stability" column. Worthiness is not simply price going up. Worthiness is price going up + doing it stably.
Silver is rated at 1.5 and Plat at 2.0. This makes them very similar. I suppose I could call Silver "Almost Good"
