500 Baht

Pick 91 belongs to the twelfth series of Thai banknotes, a series that ran an unusually long production window — nearly a decade — reflecting the relative monetary stability Thailand enjoyed before the 1997 baht crisis effectively ended that chapter. Notes from the early part of the print run and those from the mid-1990s can differ subtly in ink saturation and paper feel, a consequence of incremental supplier changes over such a long production span.

The 500 baht denomination carried real purchasing weight throughout this period, and high-denomination notes from the final years of issue were caught directly in the July 1997 float — many left Thailand as capital flight accelerated.
