Edward I (Spink auction win)

[Descartes]

Hello chaps,

Please could I ask one of the experts a question or two about my Edward I pennies I won today on the Spink auction?

First question... where it say in the provenance ii) Elmore-Jones, Glendining, 10 April 1984, lot 1582 - £65 does that mean that the second coin in the description is ex Elmore-Jones collection?

Edward I (1272-1307), Pennies (6), Berwick, local dies issue, 1.35g (S.1415); also, Durham, class 9b1, 1.46g (cf. N.1037.1 {for type}; S.1421); additionally, Newcastle (4), class 9b1 (2) with star, 1.38g; and without, 1.31g (N.1037.1; S.1408); also, 9b1/10ab mule, 1.48g (N.1037/38; S.1408/9); lastly, class 10ab, 1.25g, reading hb (N.1039; S.1409), generally very fine, all toned (6).

Secondly, please could I have a more detailed ID on coin number 5. It's listed as a Newcastle 10ab, but I'd like to know which one of the subgroups if possible (i.e. 10ab1-6).

Many thanks,
Descartes
