Depends on the book. And these are estimates, though Michael/Mschmidt had a very good reference on the Crow 1-4, and I trust his information.
Caliber Presents 1 = 10,000
Crow 1 = 10,000
Crow 2 = 7,000
Crow 3 = 5,000
Crow 4 = 12,000
Wow! I never realized how low a print run Caliber Presents 1 was, for some reason I was thinking 50,000, this book just got a whole lot more attractive to me.
Someone asked about the print run of these books.
Someday, I'll put together a run of these. Hey, I might get lucky and seduce them away from some rabid collecting fangirl too.
