I have said before I like this reference book....but one cautionary note. It appears some of the mintage information may not be correct and may require changes before the hard copy is released...unless I am wrong.
Fore example....1995 silver proof panda mintage = 2500. 1996 silver proof panda = 1000 (not sure of exact number but this is close, since I don't have the book in front of me.
Also, there are mintages for gold pandas by Mint.
