6528956125 because I let the vendor take it for £1100 last November and within 2 minutes thought - "you silly sod". Sorry, I don't know how to add links, so you will have to access it via another posting.

The Cheshire Collection that Emperor Oli is drooling over in a separate thread and currently listed on ebay is a prime example of an interest in maximising the return when selling. I'm 99% certain whose collection this is and if right, 100% certain he is English. The idea that English collectors are not interested in profit will clearly not apply in this instance - so I'm on Wybrit's side. They are all slabbed and some have been acquired and slabbed very recently, presumably for the auction. If estimates are reached, the seller will be quids in over a very short space of time -grrrr, should have bid higher.

Correct, such as dip them.

Bronze and copper varieties are probably collected more as a result of the efforts of Peck, Freeman and Gouby. There is no equivalent to these for silver coinage as ESC is virtually duplicated by Spink so there are no varieties of 1745 and 1758 shillings if the "official" tomes are to be believed, despite being two of the commonest old silver pieces in existence. This clearly isn't the case. This year Spink have added a large number of halfcrown varieties to their book. I know that these were all as a result of the efforts of one collector, so the only way to increase the amount of info in the public domain is either to pester the likes of Spink or produce a similar piece of work the above mentioned. Variety collectors will typically buy them because they know they exist rather than say I think that could be ..... and put their money where their mouth is.

I have also had a similar experience to some of the less agreeable feedbacks listed. Pictures of item did not resemble what I received (KGV florin) and that was stuck down with very gooey sellotape. That was before the floodgates opened and he then readily gave a full refund so I ok'd him at the time as he'd only had relatively few feedbacks with no negs at the time. I haven't checked his feedback since then, but panthera pardus springs to mind.

No. I haven't got round to putting it on the computer yet. As I said, I only did it to pass the time and to have a quick check on where I was up to with my collection. I was also thinking of doing something similar for shillings.

As regards getting ripped off, do the grading companies slab them to your description or their own? I have seen a couple of examples which were obviously wrong and other references to incorrectly described slabs. One example was what must have been the first known example of an Elizabeth 1st 6th issue pound with a mintmark woolpack! The problem there is the discrepancy of about £1000 pounds in VF between the 2 issues, so I don't know if it was a mistake by the grading service which was either PCGS or ANACS - I can't remember which, or whether it was submitted as a 6th issue out of ignorance or with intention to deceive. I picked up an example which was a 1675/3 halfpenny slabbed as MS64 but described as a straight 1673. This probably was a case of mistaken identity, but having said that I bought it because I could identify the overstrike through the plastic with little difficulty, so the question remains. Who does and what are the quality checks? Thoughts anybody?

I'm not aware of any quantified rarity values for individual brockages, but given that they are only produced when the manufacturing process goes wrong, it follows that they are all at least rare. They crop up randomly in auctions and so the price doesn't have a reference book value. Typically they are not in the highest grade although these are occasionally found. For young head pennies, there were 3 obverse brockages in the Adams auction at Spink in July 2003. Freeman 2 obv. toned VF sold for £80, Freeman 6 obv. gEF with a little lustre sold for £260 and Freeman 2 obv. UNC with nearly full lustre sold for £620. All prices exclusive of buyer's premium. The last coin was exceptional due to the quality of strike and extreme rarity in that grade. In typical circulated grade, a reasonable rule of thumb is double the list price or maybe a bit more than that for a normal piece. Alternatively, realistically grade the brockage and value it at the price for a normal piece but one grade higher. Realistically grade specifically excludes typical ebay grading.

Yes we should where the item is not as described to the detriment of it's value. Both for dross and for high value items if it is apparent someone is trying to pull a fast one. My own recent experience includes a Pontefract 1/- which was on ebay around Christmas time. It was high grade and worth about £3000-3500, but the seller didn't say it was plugged reducing this value considerably. I only found out when the prices realised list for the provenance given indicated that the item didn't sell at the auction. On a day when most things were 30% above estimate, this piece should have made £2K easily and so an unsold piece with an estimate of £1300 ie £700 below market value or so sets alarm bells ringing. Suffice to say a piece with the same errors in the same description (think copy and paste), but this time not pictured and with a note to the effect that it was expertly plugged appeared in the next auction where presumably the vendor acquired it. I informed the high bidder and it saved us both bidding to probably 2-3 times its value. The vendor was asked if it was plugged and he denied it, but confirmed my suspicions by sending a hi res scan. You don't casually acquire a Pontefract 1/- without doing your homework, it's just too much money to risk. A foreign seller could have been difficult to chase too. As an aside for the instigator of this thread, whom I presume is the same tomgoodheart. I am still a bit miffed over the AVSSPCE, but a good rare piece struck from different dies to Brooker 425. It looked as if it could have been from the same obverse die as 427 with the colon stops, though doubtless you will tell me.

What is the rarest coin you've seen mutilated? An enamelled 1698 OCTAVO halfcrown (R6)

£16000 hammer.

You and me both Chris. I thought the further up the periodic table you went the heavier the elements got, since lead is after gold i would have though it had been heavier. Unless it a bonding thing? Perhaps gold atoms are closer than lead ones meaning there's more in a certain area, which means that although they are lighter overall the difference balances out in gold's favour.* *That's a guess (not based on principles but just me making it up) So if i'm wrong... well i agree. Basically right. The density depends on the lattice structure of the solid which is determined amongst other things by the outer electron shell of the atoms concerned, together with an increasing density as you increase the atomic weight due to the presence of a heavier protected atomic nucleus nucleus. Based on these 2 main criteria, the relatively less dense elements in the list such as aluminium, tin, antimony and lead have s and p orbital electrons in the outer shell whereas the relatively denser ones such as copper, nickel, gold and silver have s and d orbital electrons in the outer shell. Hence you can get misconceived preconceptions of which is metal is or should be "heavier". Add platinum at 21090 kg/m3 to the previous list. It has a less complete outer shell than gold and so offers greater possibilities for bonding. More bonds = tighter lattice. Not a full explanation but hopefully clear enough.
