In the mid-1920s, postal rates worldwide were changing frequently as world economies moved closer to the Great Depression that hit in 1929. Consequently for the postal historian, this is a fascinating period in which to study the interaction of politics, economics, and postal charges.
A 70c Registry Fee?
The Luxembourg Postman’s Calendar for 1926 (excerpted above) indicates that the 1926 domestic registry fee was 70 centimes, an increase of 20 centimes from the prior 50-centime rate. When was this 70-centime registry fee in effect? From the Basien-Hoffkamp rate book, we know that an 80-centime registry fee took effect on August 1, 1926. Was the 80-centime fee preceded by a 70-centime fee? If so, when did the 50c rate end and the 70c rate begin?
Here is an example:

Update. Dieter Basien confirms the 70-centime registry fee, thus:
01.10.1925 0,50 F.
01.01.1926 0,70 F.
01.08.1926 0,80 F.
