The method is easy. A dash (-) such as 1919- means 1919 No Dot and 1920- means 1920 No Dot. Sometimes the letters ND are used.
For Dot Below it is always referring to the bottom scroll and is usually abbreviated as /.    Such as 1919/. and 1920/. Sometimes the letters DB are used
Double Dot is referring to a dot above the top scroll and a dot below the bottom scroll. It is usually abbreviated as .//.  so that makes 1919.//. and 1920.//. Sometimes the letters DD are used.
The remaining 2 dot positions only occur in 1920 and they are the Dot Above  and the Dot Above Top Scroll.  The Dot Above (DA) is also often called the Dot Above Bottom Scroll (DABS) and is usually written 1920./ but may also be written as 1920/./
The rarest dot position is the Dot Above Top Scroll (DOTS) and is usually written as 1920.//

There is a possibility this one is a double dot with a filled bottom dot AJ. I've learned from others here the dot above top scroll coin often displays a weak top scroll on the right side where as the scroll on your coin appears strong. The rim also appears a little flatter or wider on the dot above top scroll coin.

A good marker for the double dot coin is two raised and angled parallel lines above and within the confines of the outer strokes of "W" in COMMONWEALTH. If these lines are in place it's most certainly a double dot, and there will most likely be a spur on the second "N" of penny.

Somebody :angel: wrote a CAB article earlier this year where it was pointed out that most (over 80%) 1920 double dots have a spur (die clash) between NN and the Dot Over Top has never been seen with a spur.
Also if the top dot is large it is a Double Dot as the Dot Over Top Scroll variety has a petite dot.

You certainly did Neal, and most of us would be none the wiser if you hadn't. :good:

Thanks team, I did notice the NN on two of the 1919 but will have to suss them again, and again, and again just to be sure :good:

will have to have more of a suss yet but found a few in both the 1919 & 20 with this mark so I take it your talking about this N mark between the NN's..gee I hope I have one of the big one's :) But knowing my luck!

Hi Ausjack, that is a nice strong single spur. Spurs have been observed on 43 different die pairs for 1920 but fewer than 10 are that well defined.

Cool, thanks Neal :good: Not that I have many but I'll see what else I can find on them and with a bit of luck :winkextra:

I thought I'd found a few die clashes :blush2:

That coin before was a 1919 and I'll put the rest up later but this is the only 1920 I could find for now and don't know what I was thinking when I said die clash as I meant like a double strike but don't worry about me I get lost easy :) Thanks heaps for your help trying to work this out team, appreciate it :thank_you:

have you got a new camera AJ?
your photos have been great
Title: RE: 1919 & 20 dot and dash
Post by: nealeffendi on December 25, 2014, 10:56:27 PM
AJ, that isn't a double strike but a double clash. On 2 separate occasions the dies have clashed together and between those clashes the dies have rotated  to align in different positions and the 2 spurs show the 2 different alignments.
The dies may clash many times but if the alignment doesn't change only a single spur will be evident. Of course if the die clashes many times in the same position it might be the cause a stronger spur.

Thanks Neal, so I was right the first time, gee I find a lot of this a bit confusing to say the least but very slowly working it out :good:

And thanks RG but no mate, still the same old camera but trying to keep it a bit more steady when taking pic's, mind you I still take 50 pic's to get one good one :dash1:
