Tin Halfpenny Thicknesses

[Rob 3,152]

Could as many people as possible who possess a tin halfpenny please PM me or post on this thread the thickness of their piece(s) together with the edge reading or fragment thereof if legible.

Thanks.

I am making this difficult for myself as I only have an imperial micrometer, but my 1690 measures 36 thou which by my reckoning comes out to 0.914mm. The coin is very worn and the edge inscription wholly illegible.

Sorry, on reflection that just didn't look right and the micrometer is very hard to read/understand. The correct figure is actually 81 thou or 2.06mm.

That seems too thin. I would have expected about 2.5 mm as near the bottom end. What is the weight?

Sounds like you need some of my wonderful digital calipers too. Finest German quality (and we know how accurate the Germans are reputed to be) and only £25 plus postage. Hussulo already has a set (en route).
