Makes you wonder where RAM gets their figure from. Supposedly 1988 20 cents was released for circulation - mintage of just 200k...

Yeah I'm not sure about the 1988 20c piece - if there are mintage figures I can only assume they were produced but they probably suffered the same fate as the 1983 and 1984 20c pieces. Certainly I haven't found one in change either.

I have two examples of the 1985 20 Cents, both in proof and uncirculated.
The uncirculated has no bag marks, so I can only assume that it must have come from a mint set.
Rennicks reports that 2.7 million 1985 Maklouf Platypus 20 cents coins were issued into circulation, and 170,000 mint sets were produced.

Like McDonald's, Rennicks relied/relies on the RAM's, alleged, annual production figures of all denominations of coins that were minted. However, the value of eg the 1983 20c indicated in their publications is far greater then, say, the 1981 20c which has a similar mintage. The RAM's annual final mintage figures were always unreliable - have a look at what the RAM's site states that the 1992 $1 minted was a MOR's ? Yep, very, very untidy !! Another intertesting anomaly in question is the 1994 20c. I have serious doubts if there were ever 14.22 million minted. I remember getting a few in my change from a supermarket ( I was a very dedicated soul back then, so of course, I went back and got as many as I could ) when they were first released, but getting any more soon after was short lived. These 1994 20c weren't the usual high CH UNC quality you'd rightfully expect to get from a newly released coin - they were just ok, although many of them had slight obverse markings I've found on a few too many 1993 20c from mint sets. Also some of the 1994 20c looked like the substandard quality 1985 50c when they were released.as though the Copper/Zinc/Tin mix used to mint the coins somehow had cement mixed in with it by mistake. Strange light gray colours here and there on the coins with streaky feint lines, again, a bit like most of the pock marked poor quality issued 1985 50c.

apologies. I should have written " Renniks " ... " Skinner " backwards, as we all know.

Yeah,i think many mintage figures under/over lap as far as the dates go.Not something I care about,life goes on,but a family Friend was a Antique/Stamp/Coin dealer back in the 1950/70's and he was passionate about the Mints 'guestimate' figures,particulary the Sydney Mint post WW1 where alleged corruption and Fraud was rampant. Another hobby horse of his in his later years was the 1919 Double Dot Penny,he had Friends that were Teenagers in 1919 and serious collectors and like himself had never seen a 1919 DD until the early 1960's,where the heck did they come from in numbers 30+ Years after the Sydney Mint closed?

I don't think the 1994 20c is particularly uncommon - I see them regularly enough. Still, it's possible they were produced on old planchets - assuming there was a production of 1988 20c pieces which was supposedly cut short, there would have been a surplus of planchets until more circulation coins were needed. Six years of bad storage could leave them looking a little worse for the wear.

Makes one wonder what happened in 1985. Production of various coins were literally stopped. Maybe RAM struggled with the production with the dollar coin introduced in 1984? Or perhaps when the Canadian Mint and Llantrisant probably had a bit of an overproduction in 1981, hence not requiring too much coins in 1985?

I'd never thought of that but yeah production in 1981 was certainly quite high. 1984 and 1985 dollar coins do seem well-produced though (I think 1999 was really the only year where dollar coins came out a little sub-standard - they've aged very poorly in circulation).
I was never too sure when the switch to imported planchets happened either but I got the impression it was around the mid-1980s.

I guess metal price has to do something with production. I believe copper and nickel prices started to climb up early 1980s. Reminds me of the US copper cent composition change in 1982. Perhaps RAM needed to find ways to cost cut against the rise of metal prices.
I also believe there is some kind of difference in the planchets. 1981 20 cents is a good example - Canadian Mint and RAM coins wear and tone quite differently. Would be interesting to do a XRF test to do comparison test.

I think the $1 & $2 planchets were coming out of Korea but not sure when it started.There was a story about 10(?) years ago that some of these Korean Blanks were ending up in China where they were forging Oz. Dollar & 2 Dollar Coins.The story did not go anywhere and I can't find it on Google but someone on here may know more. Perhaps the guy in the link below was correct and the Govt. supressed all Info.,that's what what they did with the scandal in the Note Printing Australia Co. https://quirkylittleme.wordpress.co...-conspiracy/https://en.wikipedia.org/wiki/Note_...ng_Australia

Yeah zinc and tin were mentioned above - I thought the cupronickel planchets were nothing but copper and nickel but I guess I wouldn't be surprised if the composition has changed at times. Quote:

I don't remember that but it seems plausible - nothing to stop any company ordering the same blanks I suppose, and obviously they have to cost less than face value. But that $2 coin conspiracy isn't right - that same HH also appears on Cook Islands $5 coins and second reverse Cook Islands 50c pieces at least.

I don't remember that but it seems plausible - nothing to stop another company ordering similar blank planchets. I haven't heard of fake dollar coins though, and the fake two dollar coins seem to be dated early 2000s from memory.

For what it is worth, I have noodled both a 1983 and 1984 20c out of circulation in the past 3 or so years. Their condition is about what I would expect for their age, but I suppose they could have come from mint sets at some point, but that would have needed to be some time soon after the '80s judging by their condition.
