2017 MARKET UPDATE:
This book is STILL an under-valued key issue, despite the DD series being extended, and while it's certainly more common than other Marvel #1s from the 1960s, it's becoming harder to find at affordable prices.
The white cover does make it genuinely tough in higher grades. Try to find one that presents well from the front and which is free of stains and dust/sun shadows.
Marvel's Daredevil TV series dragged this comic book kicking and screaming into the limelight.
Sure, only a handful of back issues have value (including the origin and first appearance of the Purple Man in Daredevil #4, and Daredevil #168, 1st Elektra) also on the Hot 100 list), but there is no doubting Daredevil #1 is a Marvel mega-key.
