100 Taka

Bangladesh Bank introduced a redesigned 100 Taka series in the early 2000s as part of a broader effort to standardize security features across higher denominations following documented counterfeiting pressure on the preceding issues. P#37 is the 2001 dated version within that series, distinguished from closely related picks primarily by signature combinations — a detail that trips up collectors who don't cross-reference the signatory pairings against the correct catalog entries.

Watermark-only security on a 100 Taka note was already considered minimal by 2001 international standards, with neighboring central banks having moved to security threads years earlier.
