> This used to be the standard keyboard layout in the Netherlands, but at some point (seemingly, during the late ’90s), it was abandoned in favor of the English (US international) layout, laid on top of ISO keyboards (although ANSI units are a common sight and ANSISO models can be spotted every now and then). Worse, the keyboards commonly sold in that country print the legends for the regular English (USA) layout, with the only addition of the euro sign (€) on the bottom-right corner of the 5 % keycap. Why aren’t the rest of the tertiary (AltGr) and quaternary (AltGr‑Shift) layer assignments printed is a mystery, but cost-saving and laziness are quite probably to blame.

I assume it’s because:

1) those symbols are rarely used in the Dutch language, so there’s no need to label them

2) pre-euro keyboards were presumably simply US keyboards (IIRC guilders were simply denoted by ‘fl.’). With the introduction of the euro, there came a need to type its associated symbol, which then led to the € symbol being printed on the 5 key (and AltGr being printed on the right Alt key).
