While it goes without saying that this is an uncut sheet of fractional currency (specifically 25-cent notes), comparison to other uncut sheets suggests that this particular one has had the outer margins, which were typically fairly wide, trimmed down very close to the outer edges of the twelve peripheral notes. It is tempting to provide an overall grade of "AU", but as is sometimes the case, there is more to this story than mere "grade".
Since they became a popular collector's item in the 1960s, fractional currency sheets have always been scarce. But in a bittersweet sense, the scarcity has only become more prominent since the advent of certification at the grading services. Once the services began "creating" grades that exceeded "gem CU" -- which is to say, CU-67, CU-68 . can you say CU-69?? - the entrepreneurial spirit caught on with some speculators who realized they could cut these sheets up themselves, taking great care to trim the notes very precisely, thus creating individual notes of exceptionally high grade.
Typically, the inner four notes of an uncut sheet of sixteen (such as the present example) may yield four "super-grade" CU notes, while an uncut sheet of twenty may yield six "super-grade" notes. In a typical super-heated certification-crazed market, a single CU-68 could bring more by itself than what an entire uncut sheet costs. The point is that while an overall grade of "about CU" may be apt, the truth is that the innermost notes could hold that all-important super-grade potential.
In preparation for his second edition of A Collector's Guide to Postage & Fractional Currency (the highly acclaimed reference and de-facto standard for collectors of the series), author Rob Kravitz performed a survey of known sheets and accumulated the following
