There aren't many options (0, 6, 8 or 9) so I'm going for 5 over 6, but if anyone has a better example to confirm it would be appreciated. I'll also clean the muck off it and try again.

Hobson's Choice is well..... no option. Take it or leave it. But there is a small window where say only a handful are known and you find an example only to discover it has been cleaned/mounted/AT etc. The first is simple if you are a completist, you have it. The second situation is not so clear cut. I suspect the decision will also be influenced by your knowledge of the alternatives available.

Oh dear Not for me either, but it would be interesting to hear members' viewshow they would treat the situation where a must-have coin was an AT coin

Doesn't do anything for me I afraid Rob. Just looks like a battered 5 to me. With the dirt fully removed, I concur. Forget this one.

Sky blue? It is uniform and overall. It may be a cleaning agent residue rather than deliberately AT, but it dosn't look very natural in hand.The blue is highlighted because of the change in relief on the design, but is in the fields too.

If you want an example of AT copper, here's one slabbed MS63 by NGC. I left the sticker on the slab (seen on the rev) as I assumed this was the colour ordered.

On a more serious note though, does he really need 6 images to show off a corroded 2p? Little wonder he started it at $6.99 as his fees for the extra images must come to nearly that. I notice the postage costs are even higher than that. I assume that's because he has to send such a valuable piece by the American version of Special Delivery? Like this? http://www.google.co.uk/imgres?start=150&hl=en&biw=1920&bih=914&tbm=isch&tbnid=t9I0sS7kfPvQfM:&imgrefurl=http://www.raleighscrapmetalrecycling.com/&docid=dc4iAls5kkKftM&imgurl=http://www.raleighscrapmetalrecycling.com/images/slider/slide-5.jpg&w=964&h=340&ei=zDNoUs_LAcTX0QW_ioGwCA&zoom=1&ved=1t:3588,r:53,s:100,i:163&iact=rc&page=5&tbnh=133&tbnw=348&ndsp=39&tx=164&ty=92

1811 Frome Selwood shilling token

Cromwell shilling

Cnut quatrefoil from Crewkerne

Oxford 1643 K28 halfcrown

York 2F halfcrown

1807 silver proof halfpenny

If you like shillings, here's another.

This is crap then. Colours are all over the place. The sky is blue with a big patch of yellow - whatever next? And the sea really is the Red Sea. Naughty old Peck and the dirty vicar from Tewkesbury for doctoring this coin long before it became fashionable.

Am I the only one to think that that is ridiculous? What is the argument that it should be other than 50-50? I'm amazed the coin contributes as much as 20% of the score, let alone the reverse only. I thought it was all to do with marks out of 10 in the Warhol-esque abstract art section. It certainly has bu**er all to do with the contents of the slab on too many occasions.

If you want an example of the contradictions posed by the TPGs, you need look no further than the last Goldberg sale. lot 4329 http://images.goldbergauctions.com/php/lot_auc.php?site=1〈=1&sale=75&lot=4329 was slabbed MS65. The following lot was slabbed unc details and struck from the same die pair. Both had raised lines in the obverse field from die polishing, both had a couple of small digs to the obverse, the first by the mouth and cheek, the second behind the head above the ties. Otherwise they were practically identical, and there are no surface hairlines on the second coin other than the raised ones mentioned. It is a lottery, so don't be surprised when they don't agree with your assessment. Play the game and use your free thinking to your benefit as it works all ways. The wrong (low number) label means a cheap coin. A crap coin with a big number label is still a crap coin which you wouldn't want anyway. Let the number chasers buy it as it gives you one fewer competitor on the next one.

It should be a farthing. No pennies, halfpennies or fractional farthings were struck in 1850. Presumably the diameter is about 21mm?

With 42 examples of 'Rare rainbow patina' listed out of 70 listings in total, one might question the use of the word 'rare'. The atmosphere in Finland looks as if it is dodgy too - still, at least the EU's environment police can get a handle on that one. The only good thing to come out of all this AT madness is the preference for doctoring modern coins to achieve a level of toning that few would ever reach in a 100 years. The huge mint outputs mean that a shortage of an individual type is unlikely to result, whilst those that wish to waste money on a tacky fairground trinket are also catered for. With business expanded and more people catered for, the market is working folks.

1905 would be your Key date for the halfcrown. Liverwho? Liverpoo Sorry - intermittently defective l on the keyboard.

All the other 3s have the angled stroke such that extending it hits the end of the bottom curve. One (presumably the 'open 3') doesn't. And going back to my original point as to whether this is 3 over 2, there is a diagonal line on my screen across the upper part of the bottom curve which continues into a curved line in the field. Following the curve round you hit the left hand end of the top bar of the 3, and this is in higher relief. Taken in conjunction with a roughly straight inside 'curve' to the lower part of the 3, this would be commensurate with a filled in 2 and overcut with a 3.

Probably looked at Spink or CCGB etc. IND IMP was dropped from 1949, so comes under a different reference number
