2 New Finds! But I Don't Know What They Are?

I just found that the $2 looks like roller marks but do we get them on australian coins? Rrrr I'm going to bed so sleepy

Thanks for the info on the $2 its pretty cool looking in hand.
With the other I know there is a 1979 Australian 20 cent struck on Nepalese Rupee planchet. 7.52 g but dose not add up with mine if there was one muck up there could be two I sent pics of to a dealer but its been three days now and I haven't herd anything I might have to send it of with a few others that need looking at. Now to find out what to do and how and were to send them them.....

Hi gxseries, No when I opened my wallet to put all my coins into the money box I spotted that it was a bit thinner than the others I have had it for about 8months and just cant find anything on it

I have conformation form the Australian Royal Mint that there is no other and they have not seen one of these 20 cent coins. Its going to be slabbed but not 100% sure on how it will happen ill hear back from Hong Kong PCGS I dare say tomorrow the US expert wants it submitted and there very keen for me to post it to them or to a authorized dealer before any testing from the mint but I dont think ill let the mint test it because they said in there email it could possibly do damage to the coin. So thats where its up to... thought id share even though this is the 3rd post in a row by myself.

Frankly it couldn't have been manufactured from a Singaporean fifty cent blank as Singapore issues it's own coins and it has not been outsourced to the Royal Australian Mint for production at any point from the research I have done. Now if there was one struck from a Nepalese blank which measures 7.52g while this one weighs 9.56-7g it is impossible to be made from a Nepalese blank (the machines used to produce these coins would get it within a small range of 0.01's of from the target but it is highly unlikely one would be struck a couple of grams of! and then get through quality control would be nigh on impossible!

I am fairly sure it's an elliptical clipped planchet.

Please specify which dealer it was as use to work for the Australian Mint is a pretty ambiguous and vague term in my opinion Also in terms of an underweight planchet I would be highly highly sceptical of that as in the multiple years I have spent within the hobby I have never come across a genuine underweight planchet I mean even back in 1910 the time of our first silver predecimal coin they could manage to always maintain a consistent weight and even in 1979 with even more advanced machinery designed to maintain the very slightest margins of error a coin to 0.1 or so of a gram to spit out a coin not 0.5 nor 1 nor 1.5 grams below the standard but close to 2 grams of equating to an massive 18% error I am absolutely convinced it was not mint made in any capacity. Secondly another reason for the underweight coin may have a common theme with one of shanew coins found in a bulk lot in which a coin retained all of it's detail but was only half the thickness of a proper coin which was concluded was due to subjecting it to an acid bath of some sort. Tho could you please post photo's of the rim and that should answer a lot of questions and doubts about the coin itself.

I should add that I see clear evidence that this coin was struck underweight rather than being damaged afterwards. I also see evidence that it was rimmed while underweight. An elliptical clip (where a part of the planchet is removed that looks like a crescent moon) clearly explains everything that I see on that coin.
