The missing "IEOM" inscription on this issue results from a transitional moment in French Pacific monetary administration — the Institut d'Émission d'Outre-Mer had only been formally established in 1966, and early production runs preceded the full standardization of its branding across the series. Subsequent issues corrected this, making the without-IEOM variety a one-year type confined to 1967.
