OK first let's talk about the word "Rare" which is so commonly associated with every single coin today.
All US Gold Mint Errors are...
yet the most common "Rare" AGE error would be the 1999-w $5 and $10 struck with unfinished proof dies, which upon discovery was considered perhaps the most significant rarities of the 20Th Century. These sell on the web from sub $1K - $4K on a regular bases depending on grade, and PCGS Values is $10K for a MS70 $5. Now if you take the population reports of all the top 4 TPG services of the $5 and $10 1999-W's in MS67 through MS70 it would total close to 15,000 that have been encapsulated.
You do the math as in my book, that's not even medium "Rare".
The definition of a "Rare" used to be a coin with a population of less then 75, past that it was just a bunch of harder to find key dates.
Now the Definition of "Unique" is 1-3 Known.
This
2006 $10 American Gold Eagle “Mint Error” NGC Mint State 69
is a bit of a different story as it actually has a
Chuck of White Metal Struck-In the Reverse of the coin.
"Unique Mint Error"
This lovely specimen is a gorgeous gem which has been certified by NGC as MS-69.
It is boldly struck, fully lustrous, and reveals just the faintest hint of copper oxidation near the white metal.
US Gold coinage is struck and treated with the utmost careful inspection prior to leaving the mint.
Yet the number of Unique Mint Errors actually escaping the mints has remained extremely small within the 21 year history of the American Eagle series.
This is a coin that will have anyone who sees it state of amazement.
The asking price is calculated based upon other Struck-in coins, as there is no real value price sheet for such a rare 1 of a Kind occurrence.
A date-less heavily circulated NGC Bison 5c is on the Bay right now with a bristle from a die cleaning brush struck into the coin at a ask of under $500.00, a AU common date WLH from the 1940's with the same type bristle strike in is on a dealers site at a bit less then $2000.00.
2 Brown AU Wheat Cents with a splatter of silver struck-in have sold for over $1500.00
So now this here is a US Gold coin in a MS69 grade level of perfection with a chuck of white metal, and where are you going to find another?
