Question on Japanese Puppet State China coins

I have a friend has two China-Japanese Puppet State/ Manchoukou coins. Both are dated 1944 and are 5 Fen. One is the small 5 and the other is the large 5. KM#A13 and grade in the Fine range.
How accurate is the Krause pricing on these coins? My understand is these coins don't come along for sale too often and I have the opportunity to buy them.

The 1944 5 fen brown fiber and red fiber coins are very difficult to locate in problem free condition. Almost impossible to locate in uncirculated condition.
