1920 English Obverse

[Basil]

This particular Coin has some minor differences to my other Eng. Obverse's egs.,i was just wondering if its a standard 'dot under' example. TIA.

Die chip top of E in Penny. About 1 in 3 are from this pair

[Basil]

Thanks Neal,i assume its a 'Dot Under'?,although it looks like a Dot it won't show under magnification.

Is this Die chip you are talking about?

 

[nealeffendi]

No, the chip is towards the left on the top of the E.
That variety are all dot under.

[autocoupler]

It also has the diagonal die crack through the  A of COMMONWEALTH. There are also examples with just the die chip above E but without the die crack through A, so your coin is no doubt a later strike. This particular reverse is not found paired with the obverse that displays the die crack through IN of IND to my knowledge.

[Basil]

Thanks all,another variety i've never worried too much about in the past.

Die chip top of E in Penny. About 1 in 3 are from this pair

1. Does the "Die chip top of E in Penny" only occur in one die pair i.e. English DUBS?

2. Does 1 in 3 refer to all English die pairs, all English DUBS die pairs or maybe something else like the total number of specimens found?

For instance can we infer that there are 3 English die pairs or 3 English DUBS die pairs altogether?

Neal would be best to answer this, but I'll just muddy the waters a bit.:angel:

1. As far as I know

2. English DUBS die pairs maybe I think

[r9453]

Muddy Waters sang, "If the river was whisky and I was a diving duck, I'd jump right in and never come up"

I reckon the first one has to be a yes, after all its a die crack which ought to be unique to just one die.

Hehe, daffy always admitted to being greedy :biggrin:

The variety with the die chip is about 1 in 3 of the Dot Below English. The variety with the die mark through IND is about 2 in 3 of the Dot Below English and there are 3 known die pairs with the English obverse (the third pair being the really rare Dot Above English). I've never seen any of the three reverse or three obverse dies paired with any other die.

Thank you Neal.

So, the London obverse die is paired with two DUBS reverse dies. The "die chip top of E" type represents 1/3 and the "die mark through IND" type represents 2/3 of the total. These die pairs may or may not have been exhausted during production and in any case the number of examples extant today is what it is.

Not quite, TWO different London obverse dies are paired with two DUBS reverse dies. One obverse die has the line IND and the other doesn't. The rare third obverse die (Dot Above pairing) has a defect in FD.

[r9453]

Rats, of course I should have twigged that "IND" is on every obverse. Please be patient a bit longer, I'm nearly there.

1. London obverse with "die mark through IND" paired with DUBS reverse without "die chip top of E".

and

2. London obverse without "die mark through IND" paired with DUBS reverse with "die chip top of E". According to autocoupler this second type can also have a "diagonal die crack through the A of COMMONWEALTH" but this is optional.

3. The rare third London obverse paired with DOBS reverse has a defect in FD.

Correct me if I'm wrong but I think it might also be the case that all the London obverse dies are paired with FBL reverse dies?

Spot on for all points. Although the die crack through the A isn't exactly optional but a marker for late stage strikes from that die pair.
