Hi everyone. I want purchase a set Wisconsin extra leaf ms 67 NGC set like one in pictures what good price to buy?
There's price guides and then there's the real world. Here's a recent auction from e bay. Considerably less than 3 grand. http://www.ebay.com/itm/NGC-Extra-L...885?pt=LH_DefaultDomain_0&hash=item41968770d5
Rick Snow has some for sale, heres the link http://www.indiancent.com/index.php/wisconsin-extra-leaf-quarters.html
Keep in mind that these are not really "extra leaves" and there's no consensus over whether these represent intentional die alterations or accidental die damage.
Nice. Great prices. The NGC value given I guess were for the coins graded at MS67. All the coins for sale on that webpage were graded below that grade.
These all where intentional die gouges by a mint worker. I lived in Tucson when these came out and I found 11 in one roll which I had graded and turned into 5 sets. All MS 65. I've sold them all for about $500 per set and am keeping one for myself. If you want MS 67's don't pay more than $1200, the price's have dropped.
There is no conclusive, or even persuasive evidence, that these are intentional die gouges or die dents. That's merely one possibility. There are other curved die dents that generate a pressure ridge that are certainly accidental.
In the August 2007 issue of The Numismatist, the official publication of the American Numismatic Association, collector Chris Pilliod, who is a metallurgist by profession, published the results of a scientific investigation into the cause of the extra leaves. The evidence he gathered, much of it through scanning electron microscopy, led him to conclude the "error" was done intentionally. The window of opportunity was the time between die hubbing and final heat treat, when the die metal is soft enough that someone can alter the design with a punch tool and hammer. High magnification revealed metal flow evidence consistent with theory, while eliminating other possible causes. We are still left to wonder why someone would do such a thing.
Again, any number of other dies show curved and straight die dents that were inflicted when the dies were soft and, as a result, the impacts pushed up a pressure ridge, just like in the Wisconsin "low leaf" quarter. Therefore, the evidence Pilliod cites for intentionality is flawed. I have reported on several of these dies in Coin World. Here's a long, curved die dent with a prominent pressure ridge: http://editions.amospublishing.com/wdcn/default.aspx?d=20080303&pagenum=122&s=die dent And here's a straight die dent with a well-developed pressure ridge: http://editions.amospublishing.com/wdcn/default.aspx?d=20080204&pagenum=106&s=die dent Ken Potter reported on an irregular die dent with a pressure ridge in a Minnesota quarter. I have seen others over the years. The take-home message is that dies do get damaged while in their softened (annealed) state.
Pollard's theory may be flawed and I don't mean to debate and I certainly don't know the ultimate answer, but I found it interesting that these quarters really only came out in one batch that hit Tucson, there supposedly where some found in Texas and another state I can't verify. And all the extra leafs look the same. And there were more low leafs than high leafs. Proves nothing just interesting.
Specific die varieties and die errors typically end up in particular parts of the country. That was the case with the 1982 "no-P" dime.
IMO, it doesn't really matter what they are or what they are the direct result of because, again IMO, what really matters is the fact that they are there, They are real, and they are collectible. Folks have paid a lot more for "Made to Order" US Mint errors which, again, is OK by me.
