Talk:Treskilling Yellow

2004 edits
The TSY is certainly very valuable, cost-for-weight, but at US$71 billion/kg it is not "the most valuable thing in the world per weight or volume". Antimatter presently costs roughly $25 billion per gram, making it about 350 times more valuable per unit weight.

Several of the heaviest known elements have only been created in quantities of a few dozen, some of them only as a single atom. With each of these atoms weighing about 5 x 10^-25 kg, their cost-per-unit-weight is far higher than even that of antimatter.

See, e.g., http://www.webelements.com/webelements/elements/text/Uuq/hist.html

Most valuable stamp in the world?
I am not sure this is necessarily correct. It may well be the British Guiana 1c magenta which was last sold in 1980 for more than this stamp was sold in 1984.--Alex 14:48, 27 July 2007 (UTC)
 * David Feldman (philatelist) auctioned it for 2.5 million Swiss Francs in 1996 again, after selling it in 1984 for CHF977,500, and that seems like a lot more than US$935,000 in 1980. Try a few of these commentaries that all place the Treskilling Yellow as the most valuable;, , , , and linns that does not even mention the British Guiana 1c magenta. Thanks for the question.

 * A Z Grill was traded for a set of 4 Inverted Jennys, which Bill Gross purchased for $2.9m in 2005. . Seems to exceed the Treskilling Yellow in terms of value according to actual transactions.  Looks like all of your links pre-date that transaction.  3 August 2008.  —Preceding unsigned comment added by 76.174.43.219 (talk) 03:37, 4 August 2008 (UTC)


 * Nowhere in the link you gave does it say the block of Jenny's or Z Grill were sold for $2.9 million, it just says they are valued at about $3. Until there is a confirmed sale with a price that can be verified, what is stated in your link in terms of value is speculation and unfortunately Wikipedia is not a crystal ball. If you have another verifiable source, please bring it here. Thanks ww2censor (talk) 03:50, 4 August 2008 (UTC)


 * "On the face of it - the 1¢ "Z" Grill is a $4 million stamp. And right now that is a great deal more than the British Guiana 1856 1¢ black on magenta, or the Sweden Tre Skilling Yellow have ever sold for.  Both are unique."  —Preceding unsigned comment added by Toliveoutsidethelaw (talk • contribs) 04:23, 4 August 2008 (UTC)


 * Also, one of the sources you cited, Glenstephens.com, now notes that the Z Grill traded for a great deal more than the Treskilling . Until this stamp trades at a value about the Z Grill, I don't think you can properly call it the most valuable stamp.  —Preceding unsigned comment added by Toliveoutsidethelaw (talk • contribs) 03:46, 4 August 2008 (UTC)
 * You may be correct that the Z-Grill may sell for more but as yet such a sale has not taken place. A trade or swap is not a sale, and Glen Stephens is speculating, as are you. As previously stated, if you have a verifiable sale price, I will be happy to revise my view but until then, any current comparative values are pure speculation even by stamp dealers, as evidenced by many auction realisations that far exceed dealer estimates. Please sign you posts. Thanks ww2censor (talk) 06:06, 4 August 2008 (UTC)
 * Look, Bill Gross bought the set of 4 Jennys and immediately traded it for a Z Grill. Thus, the FMV is clearly the price he paid for the 4 Jennys.  If you pay $3m for A and immediately trade it for B, no speculation or crystal ball is required to demonstrate that both A and B are worth $3m.  I can see that you are the lord of this entry, so I'm going to leave you to it. —Preceding unsigned comment added by 76.174.43.219 (talk • contribs) 11:11, 4 August 2008
 * That is your interpretation. BTW I an not lord of this entry. Get a verifiable dealer valuation or another verifiable source that confirms what you state but until then, as previously stated, it is speculation. This is synthesis and therefor against policy. AGAIN, please sign you posts. ww2censor (talk) 16:49, 4 August 2008 (UTC)

The statement that this is the "most valuable stamp in the world" is misleading, as it implies that today this stamp would sell for more than any other, for which there is no proof. To know what the most valuable stamp is, we would need sales of the top contenders within a close period of time, and even then people could still debate the circumstances of the sales, etc. The only actual fact here, on which this misleading statement is based, is that this stamp holds the world record sales price for a stamp, and that fact (not an unprovable speculation that this stamp today is worth more than the British Guiana magenta or the Z Grill) is what this article should state. Therefore, I propose changing the statement to something like "world record sales price for a stamp," or "highest price ever paid for a stamp." Ecphora (talk) 14:15, 13 September 2008 (UTC)
 * I do not interpret "most valuable stamp in the world" to mean that it will sell today for the highest price. An actual price can only be determined by an actual sale. But if you insist then "and holds the world's record sales price for a postage stamp" seems like the clearest phrase to use. Alternatively one could supplement the current phrase as follows: "… most valuable stamp in the world based on holding the record price paid for a postage stamp." ww2censor (talk) 16:01, 13 September 2008 (UTC)
 * Done. Ecphora (talk) 17:04, 13 September 2008 (UTC)


 * In reviewing the swap of Jennys for the Z Grill, it appears to me that one might add a footnote here on that transaction which, if factually referenced, certainly suggests a greater price paid although, technically, it was a "trade" not a "sale".  Perhaps there should be an article entitled "World's most valuable postage stamps" where all this could be collected.  Ecphora (talk) 17:16, 13 September 2008 (UTC)


 * I added that the sales price is from an auction for further clarity. Ecphora (talk) 19:22, 13 September 2008 (UTC)

Wikipedia was cited in the AOL article. I think there's some kind of template involved when this happens, so I figure I'd let the editors on this page know. DurinsBane87 (talk) 23:55, 31 January 2008 (UTC)

"The number of stamps printed in the wrong color is unknown"
The famous Tre skilling stamp came from a shipping constisting of 800 stamps (8 times 10x10), wich was made prior to the next originally planned delivery, because a couple of post offices had ran out of 8-skilling stamps. A false start that was not planned. Hence, there could have been at most 8 yellow treskilling stamps (of wich only one is known). Perhaps this should be mentioned in the article. However, my english is not good enough for me to dare to change anything, as you can see. You can read about this in a book that was published in 2005, called "Den gula treskillingen" (not Sven Åhmans book by the same title), by Lars Fimmerstad. /Swede —Preceding unsigned comment added by 193.12.19.250 (talk) 08:17, 1 June 2009 (UTC) najskuplja marka an svijetu

Value in text and info box don't correspond
The info box says US$2.06M and the text says more than US$2.3M perhaps a mis type. — Preceding unsigned comment added by 41.241.162.25 (talk) 09:16, 4 April 2012 (UTC)
