Does anyone know any pricing mistakes... not necessarily typos but like those on Dutch and Portugese notes... in the Krause books?

Some of the values are way off of what is being paid.

north korean recent issues, 500 won notes and up. the most ridiculous is the 5000 won note, p-46, given a retail price of $300.00. e-bay buy-it-now price is currently at $7.00.

another example, except backwards, is tajikstan. 100 somoni, p-19, is given the retail value of $25.00. the exchange rate value is just under $36.00.
