I bought it with a group of other pennies and silver for $65 so after working out the silver value it was about $10-15 for this and about 20 KGV pennies

Thanks again nealeffendi.
Do you know of any other related issues besides the Jan/Feb 1921 and the May/June 1921?

Mr T
The only details I have for Jan-June 1921 that are not in Sharples are:
The Sydney Mint had finished striking the penny by 12/1/1921 as the logs report the last scissel (offcuts) from the coinage department.
Correspondence dated 4/5/1921 and registered on 14/6/1921 at the Sydney Mint was for the alteration of the bronze alloy composition.
Perth also received similar correspondence according to Bill Mullett.
So any pennies with the new bronze alloy composition and the date of 1920 are presumably Perth struck at the end of 1921.

Interesting - I didn't think McDonalds was right in saying the penny alloy stayed the same from 1911 to 1964.
I wonder why it changed though - I think British pennies got a new composition (or rather a standardised composition) in 1923.

Mr T
The alloy changed at least 3 times. 1921 was the first change,then during WW2 it changed (I think twice) due to wartime shortages (such as the fall of Singapore cut off the Malayan tin mines) and then after the war it changed again.
McDonalds, Renniks and Krause all get the details wrong on both allows and mintages.

Yes, unfortunately a lot of literature isn't thoroughly researched.
What was the before and after alloy in 1921?

Mr T
On page 30 of Bill Mulletts work he states that the alloy until July 1921 was 95% copper, 4% tin and 1% zinc. Thereafter 95.5% copper, 3% tin and 1.5% zinc.
He wrote that in early 1943 the shortage of tin changed the alloy to 97% copper, .5% tin and 2.5% zinc, also the 1943 halfpennies had no tin.
From 1947 to 1950 it went back to the pre war alloy and then it went back to the 97% copper .5% tin and 2.5% zinc.
BTW that is the same alloy as the 1 and 2 cent coins.
I suppose those back and forth alloy mixes might produce scarce coins near the changeover dates with the old or new alloy. That is what I'm hoping happened with the Perth minted 1920 pennies.

Would you happen to know the Sydney and Melbourne mintages of 1920 pennies nealeffendi? I've looked at a few different source and have found different values: most current books say 9,041,600 total; Jon Saxton says 5,817,000 total and Coins of British Oceania has 7,018,800 for Melbourne and 1,233,600 for Sydney. By the way, I happened across http://www.tdkapdc.com.au/australia...-london.html today - not sure if you've seen it. |

Mr T The problem is that the annual reports to The Royal Mint were done annually yet the dates on the dies were often of a previous year. I have seen the original log books for Sydney so I'm somewhat confident that Sydney struck 1,325,760 (1104.8 bags delivered) based on that many delivered from the coining room to store (it is possible that I made a transcribing error from the faded/ scratchy handwriting). Mullett has the figures for pennies dated 1920 as 1,379,760 for Sydney,7018,800 for Melbourne and 93,600 for Perth (8,492,160 all up). But I wouldn't rely on Mulletts figures as his counts for both 1924 and 1926 Sydney mintages don't gel with the log books. |

I have seen that TDK reference before. Sadly it is wrong about being a No Dot as there is the rim groove at RITT+O  |

Yeah okay, and does that Sydney figure include the ones supposedly struck in 1921 too?
I'm not surprised it wasn't the real deal but you never know.

Mr T The Sydney Mint figures include the pennies struck in 1921. On 8/1/1921 80 bags went to store and on 15/1/1921 41 and 4/5 bags went to store. Note that 4/5 bag was the only one I noted that was an incomplete bag over the production run. they didn't get new dies until 1924. And 1924 is another mess to sort out with the leftover dies.  |
