Why is no one surprised by the fact that the most popular banknotes in circulation so long been in circulation without attention to the lack of serial numbers?
Because the average person just does not scrutinize his/her money. It's a difficult concept to swallow, I know. I would also propose that people in the 1960s were not as paranoid about counterfeiting as bank tellers are today.
The image is very poor quality.
I would not say that about the full-size images (links copied from earlier post)...

P.S People who want to get a consultation or evaluation by the bill very often don't use high-quality pictures. Ask advice on poor-quality images, this elementary no respect for the forum members.
My opinion is that there should be a rule, if you want to get the advice you need to make a great scans.
It has nothing to do with respect for forum members. Just because technology exists for making high-quality images, that does not mean people know how to use it. I, for one, am inept to borderline retarded when it comes to photography, but I'm pretty good with scanners. Many people asking for assessments of notes simply don't know that we need images to make evaluations. They simply don't know any better when they register on this forum and ask "What is my 1973 $1 note worth?". If the value of notes was not so completely dependent on grade, then image quality would not be as important. But the average person who is not a collector and who seeks information simply does not know many of the golden rules about collecting.
As for making it a rule to provide high-quality scans of notes in question... good luck enforcing that rule. Most people can't even use ImageShack properly to post their images, lol. I can already envision the result of having a rule about images. People will equate image size with image quality, and they will produce the same fuzzy out-of-focus images, but instead of those images being the size of your screen, they will be 8,000,000,000,000 by 6,000,000,000,000 pixels and will take hours to download even by high speed Internet connection.
So, umm, no thanks.
What is wrong with simple courtesy, anyhow? If someone asks a question, we tell them what we need, and if they don't provide it, they don't get their answer.
