It’s probably one of those tricks of the eye, but I can’t quite figure out what we are looking at here (post #44). Why is one side grey (undeveloped?) and the other side black (developed?)? Why does the black side have distorted sprocket holes? Is it a shadow? Is the scratch in question the pale narrow line straight down the centre of the photo, and why does that look grainy rather than sharp-edged when zoomed in? What is the broader line to the left of it?
Perhaps you should take a roll of undeveloped film that you may have, pull it out if its canister and examine it under indoor lighting. That should help you understand what you are looking at.
Don’t worry, you can put it back in the canister and use it. As long as it hasn’t been exposed to light while in a camera it will be fine.
