Australia KGV Stamp With Two Missing Perfin Pin Holes.rare?

This is an Australia KGV stamp with OS perfin in a normal way.Obviously,there are two missing perfin pin holes in the OS perfin and the letter S does not look like a S anymore due to missing holes there,it looks like a coma in an inverted way and another coma is a normal way but the letter O remain back as normal.Honestly,I have never seen anything like this before and this is the first time for sure as a stamp collector.I have discovered only one copy like this from thousand of the OS perfin stamps in my collection and I would think this is certainly look special and rare to me.Unfortunely,I am not sure if this considered as a new discovery because I really have no idea and not an expert in the OS perfin stamps.I have heard before that there are a few broken perfins and used to punch on the stamps and probably the OS perfin holes with less perfin holes on this stamps for sure.Unfortunely,I still need help from the expert to identify this two missing holes and confirm that the broken pins are in a correct position and let me know what I need to know for sure.

Some times the pins break off and other times they don't punch all the way through.

Buba, sorry to say - unpenetrated or partially penetrated perfin pin holes are quite common in many Pre-decimal Australian stamp issues.

I have Australian KGV 1d's with none of the OS holes successfully punched through, only indented stamp surface.

Very common with perfin "T".
