Sorry to drag it up but I acquired a 1902 crown the other day which did have a few green spots, but nothing that had fully taken root. I agree that verdigris on sterling silver coins is unusual (I couldn't recall any examples barring my recent purchase) and probably would be due to contact with other infected coins rather than environmental factors.

It is an absolute stunner - almost perfect strike on that obverse.

I've been looking in a few places trying to work out what the edges were on crowns from 1821 onwards but can't quite seem to get it. It looks like there were reeded edges with no inscriptions in many years but what is unclear is if the various years with edge inscriptions had reeded edges or not (in the back of my mind some did but I'm sure some didn't too). Anyone know which edge inscribed years had reeded edges too? I'm mostly interested in 1887 onwards but I'm curious about the George IV crowns too.

Alright thanks for clearing that up - haven't got to looking at the early Victorian stuff yet though.

Hm, I haven't heard of that one (not that I follow it too closely) but there was an article in the Australasian Coin and Banknote Magazine about predecimal doubled dies recently and I don't think it got a mention. Might need to dig out the article again...

I still haven't looked through my Rennick's error coins but I always got the impression the author was very much into the predecimal side of things and any information about decimals was what was provided to him. Possibly part of the problem is that there are probably quite a few predecimal doubled dies that get mislabeled as re-engraved dates.

It seems to me that the predecimal doubled dies are much more popular than the decimal double dies (I guess they probably happen more frequently in modern production). I'm not too into the errors myself but things like upsets, clips and partial collars are the things that seem to sell for any reasonable amount above face value.

Weren't their later coins made to order? I got a 1982 or 1983 set not long ago that came with a pamphlet about ordering which suggested they would make as many as they got order for (and I guess would explain the non-round numbers produced).

Looks like it could be struck out of collar? Not sure how popular error coins are in the UK but here in Australia you could sell it for tens of dollars at least. Nice find anyway - normally the mint should pick this up, or at worst a security company's rolling machine should reject it - they don't often get to circulation.

Probably not - a couple of years ago I got a bunch of site hits (from which country I no longer remember) but they had spoofed some field or other (browser language I think?) to be "VOTE TRUMP" - possibly something similar. Occasionally I see fake hits that just spam the referrer field with some site they're trying to advertise - again, possibly something similar.

Yes it looks to run under the letters - struck through wire?

The Uniform Coinage of India 1835 to 1947 by Stevens and Weir is a good reference - it says that 24,144,000 1947 Bombay 1/2 annas were minted but gives it an equivalent value to the Calcutta. The David Fore Collection of British Indian coins (which was very comprehensive and was sold by Baldwins) didn't seem to have an example though (at least not in the sequence of regular coins). I wouldn't be surprised if a lot were made and subsequently withdrawn (or perhaps never even issued).

Very nice! Are those pages PVC though?

We'll see - in Australia they did a letter for each $1 for a few years (I think they may have stopped) - none circulated and they did each letter each year for a couple of years.

Thanks. Looks like it's missing the 1863 die number 5 penny.

Maybe - I wouldn't be surprised if there are more varieties these days, though I expect a lot would be such small changes that you couldn't spot them with the naked eye as they don't hand make dies any more. They could probably easily reduce the profile by 10% without anyone noticing and strike a whole lot more coins.

I'll make a note of it.

Even in Australia there are a lot of decimal varieties (particularly after the introduction of the Ian Rank-Broadley obverse). I suppose modern mints are just as interested in extending die life as the mints of last century.

Is it available online?

Looks more like a proof to me.

Couldn't agree more. I think this case isn't too bad but I shake my head whenever I see Perth Mint bronze with indistinct denticles and Queen's face in an MS slab. It may be technically uncirculated but if it doesn't look uncirculated I'm not going to pay uncirculated money for it.

What about the obverse?

I'd say EF but the colouring makes it look like it may have been cleaned.

Are the avatars that load taking a while to load?

I would agree with Freeman 1+A.
