For the second time this year the NBU has updated the signature on a circulating banknote, the 500 hryvnia in March was the first, and the 100 hryvnia is the latest note to receive the signature of the new Governor of the NBU, Kyrylo Shevchenko. The 100 hryvnia banknote was designed in 2014 and measures 75 x 142mm, this is the third signature to grace the 2014 design and is the fourth different pick # to date. The new 100 hryvnia banknotes were put into circulation on Sept. 7, 2021.
PICK # 126a
PICK # 126b
PICK # UNL
PICK # UNL
It'll be interesting to see what they do with the Pick #'s, do they assign P# 126c to the commemorative note which was released first, or to the regular circulation note? My guess would be the commemorative receives a separate Pick #, something like 126A and the latest note gets 126c. I'm also going to take a wild guess and say that in addition to the four remaining commemoratives scheduled to be released later this year, that we'll also see the release of a 20 hryvnia circulating note with new signature. A new run of 20 hryvnia banknotes has not been released/printed since 2018. We'll see, updates to come when available.
