I have learned a little bit about the typical expectations you should know about how paper money transactions occur. Unlike coin dealers, most paper money dealers do not own a store for their material thus it is common to do transactions over the phone or through the mail. I know it seems sketchy to buy something so dear to you and have it mailed without even really knowing what it looks like first hand. The good thing is that nearly ever dealer that works with the mail will be kind enough to honor a money back guarantee with no questions asked. Returning notes is common.
