Israel 5 Agorot 1972 error coin

Can someone give me any information regarding this coin

It should be 1972 (תשל״ב) But ת - is missing.

Please add an image of your coin?

Anyone?

What is wrong with the coin according to you? Please add the numista reference link?

N#1719

My coin 

with the full date:  תשל״ב

Your coin: 

I suppose, the  ת   on the die was filled with grease, thus resulting in a no print. The other possibility of a mechanical manipulation to remove the  ת   is another possibility, but there is no trace to support this, but it might have been done?

 There is a shadow of where it is 

 So yes, probably a filled die.
