The author seemed pretty convinced that many of the prices he was spotting were probably supposed to be real-money prices -- e.g, an item that was supposed to sell for $100 would instead be sold for 100 gold. (Which is a trivial amount, even in game.)
this happens more often than you think in games that have two systems that can be confused with each other. EVE online is a good example (except instead of real currency, it's just mis-typed zeros and bad UI queues)
