Beginning in June 2025, series B notes were introduced with new features designed to increase security, longevity, and efficiency: color-changing security thread with motion effect, more high-relief printed elements, fluorescent tri-color security threads, microtext, and magnetic and infrared ink. These revised notes were printed without imprint by Crane Currency in Malta.
Like B421b, but new Motion windowed security thread with demetalized 200 and macaw, no printer imprint at lower right back, and suffix B.
