Good morning (at least when I started typing).
Rod, indeed it's hard to get results for NVI with the English website version. I've mailed them and await their response.
Here's a link to a Hebrew search, You can make out the issuing date and value (New Israeli Shekel is #1513;"#1495; ).

vayolene - in Judaism there is wide use of numerology.
So the letters Taf Shin Khaf Tet are 400+300+20+9=729. Adding 7000, the total is 7729, meaning 7729 to the creation of the world. The 7000 is not mentioned in daily dates
To translate from Jewish to Christian date add 1240. 729+1240=1969
BTW, that security bond stamp should be worth something: Even nominally, 300,000,000 Lira is 30,000 NIS, a little less than 10,000 $
