Stack's in the May 11 1998 Coin World was asking an astounding
$35,000 for a PCGS AU50 specimen. They had this to say:
"The date is a great rarity in any condition. It is estimated
that there are less than fifteen known in any condition...
In our opinion, this date is the most underrated rarity in the
entire Liberty Gold series of any denomination. Within the
Eagle series, its rarity is on par with the 1875 which sell
for almost three times this date."
