25 Pfennig 3 x dissected from 100 Mark

Düren's 1921 emergency currency scheme divided a single 100 Mark sheet into three interlocking 25 Pfennig slips — each physically cut from the parent note, with the pieces designed to recombine as proof of authenticity and prevent counterfeiting at the local level. The trisection approach was unusual even among Notgeld issuers, most of whom simply printed low denominations outright rather than engineering a dissection system.

Pfennig-denomination Notgeld in 1921 reflects the awkward transitional moment before hyperinflation made small change irrelevant entirely — within two years, 25 Pfennig would be economically meaningless.
