I've checked with the auctioneers and it's 45mm in diameter.

Great.

That is good to know and explains the discrepancy of the two sizes remarked before.

What's the weight of your threepence Mal? Could this be a sixpence struck on a threepence flan?  ???

Even larger are the tokens produced for the Birmingham workhouse, a extremely rare copper sixpence, of which only six were made, along with this threepence at 44.7mm with 72.3g of copper.



I think that is about 2.5+ ounces.

...more than double the weight of that sixpence on offer.

I can't quite work out what's going on with it. Same diameter as the threepence but a much thinner flan. A later restrike? I don't have a copy of Withers - do they have anything to say about it? W376a.

It doesn't really matter because I can't afford it anyway. :(

Here is the information from Davis - 19th century token coinage.

Unfortunately no sizes as he used the mionnet scale. (two varieties of 3d mentioned but no size of either!)

Thanks Mal. I can't quite reconcile Davis 30, the thin flan version, with the one at auction.

1oz 1½dwt is, by my calculations, 30.68g. Auction example is 32.1g.
Mionnet 13¾ looks to be close to 50mm. Auction example is 45mm.

I would like auction house and others to start using the correct measurement as these days with digital callipers there's no excuse for a near enough measurement.

My 3d is 44.7mm which I have just confirmed and I expect the DNW 6d piece would also be this measurement rather than 45mm.

BTW the 3d thickness is 5.6mm

This is sort of useful  8) Mionnet's scale

I hadn't heard of it before but it's really quite odd!

I did Google it to find out, and got a rough conversion chart. I can't work out what he was thinking about to have irregular intervals though.

Probably had a big stack of round things on his desk and numbered them 1-14 in size order.  ;D

Some more big 'uns:

Roman Aes Grave, weighing a full Roman pound of copper:

This one is 66mm x 280g, earlier examples weigh over 300g.

Bactria, Amyntas dodekadrachm:


Bactria, Eucratides 20-stater:

58mm, 169g.

I know the aes grave were actual circulating currency, but I suspect the monster Bactrian coins were minted for the same reason that Australia made a 100kg coin--"Because I can!"
