2018 MOR $1 ..... Opinions of how these came about would be appreciated

[Unicorn]

I'd really appreciate people opinions on these.

These 6 fella's came out of a single RAM satchel that I bought when the RAM had it's pop-up in Port Macquarie back then. I bought 9 x $1 satchels and these only existed in the one. I'm not sure if it's a hubbing error, or a doubling (odd for doubling to be in the centre though). I'd  appreciate your thoughts on them. The pics on the far right are comparisons from a standard 2018 $1 from the same satchel.

As you can see the earring is impacted, so too the base of the hairline, back of the ear etc and the nose is a bit similar to doubling that I've seen. (Not the earring ever though).

Thanks in advance :-)

My guess is machine doubling.

Thanks Echi!

Nice photos Uni!

My guess would be doubling too but the earring impact I haven't seen before.

Thanks Pedro, yes the earring was what had me wondering. I'll have to get my head around how the doubling is at the centre of the coin and doesn't extend to the outer (my head was in the thought that if there was small movement in the centre, it would increase as it got closer to the outer ..... but Unicorns aren't that well versed in physics .... lol).

Nice find.
