Untrimmed pages and value? 0

[Atticus123]

I have a super clean copy of a comic that has three pages that were somehow not trimmed.  There is about half an inch of extra paper at the bottom right corner on both sides.  The book's were my brother's and he kept them safely boarded and bagged and didn't touch this issue in any way.  So how does this affect value?  I've had collectors tell me it both adds and subtracts so I'm just left scratching my head -- I am not myself a collector, just the recipient of this collection.  Any input is appreciated!

Some people like "error" comics. It's just another niche.

Surprisingly, this isn't all that unusual. Not a big deal...

Is it something it would be graded down for?
