UK unofficial countermarking ?

UK
I found this coin today while searching through some 10p's . Could this be classed as an unofficial countermark or is it just somebody with too much time on their hands?
There is a round mark punched into the Queen's neck & there are 2 triangular marks punched into the lettering , one below the B in ELIZABETH & the other on the last figure of 2nd.
Has anybody else seen anything similar on modern UK coins?


Thanks,
Merv

Hello, these are just some random (punch) marks with no meaning to them. They count as damage.

Other examples of similar things include this lot of Lincoln cents and you'l find much more with this search on eBay via picclick.

Somebody has deliberately done this so it is not just random damage.
Having said this, there must be some people out there that know who did it. It's might even be like graffiti "TAG".
If your mates don't know that it's you it's not worth doing it.

These marks were randomly punched on the coin and have no meaning whatsoever.
