On July 1, 2019, the private postal service “Nordbrief Kiel” issued a sheet of 10 stamps featuring the most popular stamp topics with the new 75 Cent face value. The issue was named “Bestseller 75”. Parts of the sheets had one stamp (Alexander Behm) imprinted with the face value 67ct instead of 75ct. When the error was discovered the sale of the respective sheets was stopped.
