| Comments |
Thailand's move to polymer for this denomination in 1997 came at a particularly uncomfortable moment — the baht collapsed in July of that year, triggering the Asian financial crisis that spread across the region. The new substrate was a practical decision made before the crisis hit, intended to extend note lifespan in Thailand's humid climate, but the timing meant these polymer fifties entered circulation into an economy in freefall.
Note Printing Australia has printed the series continuously from 1998. The clear window is integrated into the polymer substrate itself rather than applied as a foil patch — a distinction that matters when assessing authenticity.
