I'm particularly interested in the designs that are different than the "normal" designs (as defined by the general population). Littleton has a page that might be okay: https://www.littletoncoin.com/webap...5|-1||LearnNav|Large-Size-US-Paper-Money.html but I'm wondering if there is a better one. Notes that pique my interest are ones like: black eagle, large silver 1923, educational series, gold certificates, rainbow notes, etc.
I do not remember the site, but the US Souvenir Cards have a variety of notes with great displays.... I believe it was the site of "Ken"?
That would be Ken Barr; he's been around the souvenir card hobby for YEARS and I've done business with him with 100% satisfaction. http://www.kenbarr.com/
@techwriter, thanks! Ken Barr certainly has a lot of them for sale... Does he also have some sort of logically categorized listing of all U.S. paper money on his website? That's what I'm *really* looking for... a reference so I can easily see everything in one place so I can make a "want list".
Check this thread for a good list of books and sites that will be of good help- https://www.cointalk.com/threads/paper-currency-for-dummies-needed.295643/ At the bottom of the thread it shows the book I bought and it has been a huge help - around $36 on Amazon. It's organized by denomination and has not only pictures of the notes but a description and short history on the series before the note values. I'm new to paper currency as well and it has helped in building my "want list" and has given me an understanding on what I'm looking at when looking at bills i.e. serials, seals, features etc.
