<p>[QUOTE="robp, post: 5484678, member: 96746"]The arguments are laid out on pages 10 &11 in Peck. It's based on Snelling's conjecture that they were for a token or pledge in copper. The weight of a copper pledge penny is 28 gr., so using half the weight as a guide for something in this metal, bearing in mind they were contemplating using copper for the English coinage at this time. The difference in specific gravities between copper and silver would therefore produce a weight of around 16.0 grains, which is the average of the six silver specimens known.
