Re: OOC
I'd say so far so good. Most prices have remained the same, but for the most part the changes make sense.
Dagger/Arrows: Lowering the price is good because Arrows are always ammunition and daggers become more viable and disposable throwing weapons with the lower price.
Lights: 5 Torches to a penny works for me. A lantern and three oil flasks for a crown works too. Reduced magic torch prices are nice too. It means we won't be breaking the bank for torches or lanterns anymore. I'm a bit concerned that with lower magic torch prices people may just stock up on those instead of the even cheaper torches though.
Staff Prices: Significantly lower at the low end, slightly in the middle, and slightly higher at the end. It works. I think it keeps the staff prices more proportional to their power levels.
Another Potion Price Drop: Probably for the best. Potions are still grievously underused.
Three currency system as a whole: A good idea all around, I would say. It will make creating more mundane items a bit easier on the economic side. It also gives us a little bit of wiggle room with haggling low-end items and helps put the value of crowns a bit more into perspective.
Only things I noticed that I'm not 100% on...
Two handed weapons got more expensive: Not a huge issue. It's one extra crown, and two-handers are still damn powerful.
Light Armor Cheaper, Heavy Armor more expensive: Realistically, this makes sense. However I'm not sure how this price change will affect the metagame.
No Shield Price: Likely an oversight.
