Title just to get your attention.
Anyway,
Unless I am mistaken NCR dollars, Legion Coin and Bottle Caps have a fixed value in relation to each other, regardless of your Barter skill.
Pre-war money and casino chip value vary with your Barter skill.
So to me this means the dollars/coin/caps are treated as currency, while the money/chips are commodities.
Do you agree/disagree? Do you care? Does it matter?
BTW I find it ironic that the Burned Man is on the tail side of Legion silver coins.
And I think casino chips should have weight in hardcoe mode.
