I came across this 1969 20 cent piece in my change this afternoon. You can clearly see the indentation in the base of the 2 without any magnification.

It appears to be factory formed as there is no pressed out metal below the indentation. What are your thoughts, is this an actual error coin and is it valuable like my 1966 wavy baseline?

I see what you mean in terms of no pressed out metal.
Another example would be required though before saying not PMD.

The Australian 10 Cent and 20 Cent coins of the late 60's and early 70's often have very weak edge milling.
It is very easy to make fake errors with these coins by completely removing the edge milling and burnishing the tooling marks. There is an extremely tiny loss in weight, well inside the remedy tolerance standards.
These sort of fake errors are very difficult to detect, and for this reason, I always steer very clear of them.

I believe there is a rare 20c error called a swan 2 where part of the bottom of the 2 is missing metal but also at the neck of the 2 there is also metal missing, never seen one only read about it, maybe here.

G'day all, thought I would share this pic of a 1980 20cent piece . Had a look at Renniks Error Book and it has a reference to a 'Blob' error .
This blob is raised and all on its own next to the zero.
Is this a 'blob' error ?,any one seen a 'blob' error?

Nice find - I haven't seen one like that before.
Small die chips are not uncommon but that's quite sizeable.

Thanks for your comment MrT, Do you have a mowhawk?
Maybe a lot of necklaces?
Can you confirm it is a 'BLOB' error coin?
Really hoping it is.

Please share your thoughts on this coin

I found it in circulation about a year ago

Struck through?

My opinion is that it's just a scratch. So PMD

Small bits of metal pushed up on the sides of the 'left' scratch.

Not sure what you mean crabeater but if you flick it with a toothpick and bathe it in acetone and it still doesn't come off then I would think it is real.

coins with small rim Cud and die chips depend very much on the buyer and what they are willing to pay. Some are terrible hard to find but aren't worth much on the open market, others are due in part to the deterioration of the die and so might be much more common but up and till a certain point they are overused dies are retired so you don't get large Cud and therefore larger ones are often more valuable and rarer.

Rabbit ear is probably the better know errors that has some collectable but also quite findable.
