London Die 1921 Penny?.

Thanks Neil all good.

Funny thing you say there is one with the top scroll missing this coin in the photo may appear as the word ONE and the inner bead is worn at the top but it actually isn't its as thick as the rest of the stamping its just discoloured but the scroll is almost non existent I mean you can catch your nail in the bead and letters easily but the scroll is so flat its just about not there.
I mean it really is very faint and half almost not there at all, I cant see how the scroll could be so warn yet the bead and lettering so good.

But again thank you. I'm happy its one I never new I had , Is there any other varieties I can check for I have many of just about every year except 1930 of course.

That is the TR blob The top scrolls on many GeoV pennies are weak (like your coin) as the design of the obverse takes too much metal to properly fill and leave enough for the other side (especially at the top scroll). The missing top scroll variety has almost no scroll at all.
Now go through your other 40 pennies and see if you can find an Indian with the TR.

The 1921 penny was struck in both Perth and Melbourne. There were dozens of die pairs including a few (like the TR blob) with multiple hook up partners. Best thing about 1921 is that the alloy changed so the changeover separates the early 1921 from the late 1921 (and into 1922?).
I still have a few more years of analysis to see if I can identify the position of each die pair in the scheme of things.

For 1922 there are the various wide dates (about 3%),the Indian obverses (about 10% each from the 1920 and 1921 masters) and the FBL English normal date (perhaps 5%).
1923 is a year I am not an expert in (it wasn't struck outside Melbourne and they are all English obverses).
1924 has filled 4s,also Indians (about 8%). The majority are English obverses but there is a distinct difference between Sydney and Melbourne coins (Sydney had flat obverse rims), all Indians are from Sydney mint.
1926 is also another year I am not an expert in. They are all English obverses and they were struck in both Sydney and Melbourne (the majority in Melbourne). At this stage I have not yet determined how to identify Sydney coins from Melbourne coins as I have not yet got around to it.
1927 has the rare Indian obverse that was struck in Melbourne using a single die that had been used for some of the 1924 Indian pennies before being sent to Melbourne after Sydney closed.
1928 has lots of interesting chips on the dies, many were on the master dies and pay attention to the date and OMN. It is very difficult to find a coin without at least one chipped letter or number and some have a dozen or more chips. When the chip is on the master you can use that chip deterioration to determine if the die was an early die from the master or a later die (the chips got worse).
1929 has both English and Indian in roughly equal numbers.The Indians were from a fresh master die sent out from London. The English are often dies with plenty of chips. It needs more research to determine how many were from the old master and how many (if any as I have not really checked) were from the master used to strike the 1930 English die (and 1931 on).
