I saw this auction on Ebay and the seller said it is a "Ladder" Note. Here is the link: https://www.ebay.com/itm/2013-US-20...459935?hash=item1ee9ad2edf:g:5ZUAAOSw01Jbjy4o I know it has 3,4,5,and 6 but they are not in order. My question is: Do the numbers have to be in order to be considered a Ladder Note? Or can they be in any order as on this auction? I guess that is 2 questions. Thank you in advance for anyone who replies.
