On September 16th, 2014, the Israeli Ministry of Finance (along with the Bank of Israel) introduced a new bank note for the 50 NIS (New Israeli Shekel) value.
This was introduced as an "upgrade"/replacement for the current (now "old") 50 NIS bank note.
The theory behind the logic of the change was that this note is so much harder to counterfeit (and more accessible and possibly other reasons. Doesn't matter...)
This was actually so exciting that articles were written about the "security" of the new banknote - for example this article.
And in fact, the note was so secure, that it took all of 5 weeks before the first attempt at counterfeiting took place, as described here.
