Guest john field Posted March 28, 2004 Posted March 28, 2004 i have an 1818 crown with one side upside down is this common? Quote
Emperor Oli Posted March 28, 2004 Posted March 28, 2004 Yes, this is what's known as the die axis. In this case it is Up-Down (that meaning the obverse is facing the right way, but when you turn it around, the reverse is upside down). If you attach a picture, we can value it if you want but you'd have to also include the edge inscription with it as there are many varieties. So in conclusion, it is common - it would be rare if both sides were the right way around! Quote
mint_mark Posted March 28, 2004 Posted March 28, 2004 Hi John, upside down is usual for those crowns.If you have to turn it top to bottom to see the other side correctly then that is called "coin" rotation (or up-down) and if you have to turn it left to right then that is called "medal" rotation (imagine a medal suspended from the top).Mostly some countries do it one way and some do it the other but occasionally they change their minds and sometimes you can get both orientations in one issue of coins, but it's only scarce or valuable if they were all supposed to be the same and a few were done the other way by mistake.

william Posted March 28, 2004 Posted March 28, 2004 Why do some English predecimal coins have 'up down', and some 'up up'? Quote
Guest john Posted March 28, 2004 Posted March 28, 2004 thankyou for your info on my coin but sorry im not selling it. ive only just started collecting and am just interested why. Quote
mint_mark Posted March 28, 2004 Posted March 28, 2004 I don't think there there is a technical reason... it must just be a matter of how the dies are mounted in the machine (is "press" the correct name?). If it was just up to the person fitting the dies then we'd see more variation, since any one issue uses several sets of dies. As well as up-up and up-down sometimes you get mistakes where the sides of a coin are rotated by an unusual amount (say 25 degrees) with respect to each other, and these are usually considered errors. I have an early 20th century Chinese coin like this, but with that issue spelling mistakes are common, so I imagine they just didn't bother about the alignment.For coins where they do bother, I think of the alignment as part of the design. Up-up is just a convention, like changing the direction of the monarch's head, but we didn't always do it that way. Quote

Up down is called 'coin alignment'up up is called 'medal alignment'Up down was traditionally used for coins, whilst up up was used for medals and special strikes such as proofs.British coins first tried up up alignment in 1787, but for the most part reverted back to coin alignment, until 1816 when some coins were minted in medal alignment again, by 1821 though coin alignment was back in for the most part. It wasn't until 1887 that medal alignment was accepted as standard. Quote
william Posted March 28, 2004 Posted March 28, 2004 Very interesting. Thanks Sylvester and mint_mark! Quote

Unfortunately I don't have a complete set of dates and none of my books mentions it. I don't have two denominations from the same year with different orientations... so the question is, is this a per year difference or can you get some years with both orientations? Also, was it a deliberate design change or an accident?I should point out that medal rotation is by no means universal around the world... up until they adopted the Euro the modern coins of Spain and Portugal were coin rotation, but even they changed their minds now and again over the years Quote

(he's into Jersey coins mostly)Post your question here...http://groups.google.co.uk/groups?hl=en&lr...ollecting.coinsGermany had coin alignment too until it got Euroised, no?And our good friends in the US still use coin alignment.

Emperor Oli Posted March 28, 2004 Posted March 28, 2004 I've just noticed the forum's clocks aren't forward Quote
mint_mark Posted March 28, 2004 Posted March 28, 2004 Dunno a thing about Guernsey coins, but i bet Harold Fears might... (he's into Jersey coins mostly)His website about Jersey coins is truly amazing... he researched original documents from the royal mint records to verify mintage numbers. That's where I went to learn about why Jersey started with 1/13th shilling coins and changed to 1/12th shilling.http://www.jerseycoins.com/ Well worth a visit! Quote

Geoff T Posted March 30, 2004 Posted March 30, 2004 The latest edition of Coincraft's "The Phoenix" freesheet describes the Gillick head as being the Machin head several times in one section (but then it does appear to be written by people who wouldn't get through GSCE English). Quote

Ah some people!You know i never thought much of the Gillick head at first, but the more of it i see the more i appreciate it! It also helps if it's well struck and the Queen doesn't look naked. Once you realise she does have a jacket on, but if you spent most of your early collecting life looking at worn florins you'd never have guessed! Quote
mint_mark Posted March 30, 2004 Posted March 30, 2004 I was always disappointed at how poorly struck the 1953 coins seem to be Quote
