<p>[QUOTE="robp, post: 20305258, member: 96746"]1860 Weyl pattern penny with a milled edge and struck in tin. Catalogued in a Glendining sale in 1993 as being aluminium, and subsequently repeated in sales since then. Presumably this was on account of Peck only recording aluminium due to the BM's coin. The weight at 10.40g is approx. 3.25x too heavy for the lighter metal, leading me to carry out an EDX test of the metal proving it to be tin. See my article in the 2011 BNJ. Ex Murdoch, Roberts & Adams collections.</p><p>[ATTACH=full]1540495[/ATTACH][/QUOTE]</p><p><br /></p>
