Item 1966/1 - Three letters from W. J. W. Potter

3 items, paper

Three letters from W. J. W. Potter:
(a) typescript, one folio (recto & verso), dated 7 January 1966, in response to queries of IS regarding the earlier work of WJWP with Edgar J. Winstanley on the coinage of Henry VII. The specific points that WJWP addresses concern "compound mark groats", the dies of the "rose groats" and "type II groats". There is some discussion of die output and more lengthy consideration of die linkage involving modification of the die between the strikes represented in two coins.
(b) typescript, single page, dated 9 January 1966, following up on the earlier letter of 7 January and explaining the rationale for the order of the mint-marks "between cross fitchy and cinquefoil" is provided "by the change in the crown and by the succession of die-links". The lettering of the sovereigns, he continues, is identical to that of the groats with the same marks.
(c) manuscript, one folio (recto & verso) dated 10 April 1966, congratulating IS on his "excellent article in the [Numismatic] Chronicle" and further discussing the question of die output.
