Neat but I have to ask if it is authentic?
As @1993Z mentioned, this issue is one-sided, so that won't help you identify fake notes.
To quote myself from an old post:
"For these and other obsolete notes, you have contemporary counterfeits, spurious notes, altered notes, and reproductions. The first three are old (fake) notes, and reproductions are modern. Contemporary counterfeits are attempts to make fake copies from the time the actual note was in circulation. Spurious notes are fake notes that did not attempt to copy a real note (a totally made up image with the name of a real bank). Altered notes are...altered...usually a legit note from a bankrupt bank that is changed to look like it came from a valid bank. The North even issued fake confederate currency to destabilize the market. All of these old fakes are actually collectible to a certain degree if you can correctly identify them for what they are. Oh, there are also remainders (unsigned and unissued notes) that were subsequently forged with signatures."
So the only thing I might worry about with this uncut remainder sheet is a modern counterfeit (as opposed to a known reproduction). If there were a lot of them, it would be added to the online lists of fake notes within a period of time. The image appears through from the reverse, so it looks to be the thin rice paper that was used on many of these notes. Bottom line, it is printed on paper, so there is always a chance to be fooled, but nothing sticks out as wrong with this note/sheet.
You can look at Heritage Auctions
