While editing the Bangladesh chapter of my new catalog of world notes, Bill Stubkjaer and I confirmed that his example of the Bangladesh 20-taka note of 1979 (Pick 22) has an error in the printed solid security thread. Specifically, the words BANGLADESH BANK are repeated on the thread, but the Bs are backwords and BANK is spelled with an X, not a K:
I’d appreciate it if collectors would examine their own examples of this note and report if varieties exist with the correct spelling. Please post comments with your findings either way.
