On dig4coins.com i have recently read that the black eagle note turned into the second most expensive paper money of its kind, sold at an auction on december 10'th. unfortunately it's not mentioned who was the buyer of the 1899 large size note and the real price. i would appreciate if you could help me with the buyer's name and the final price. it is said that it was sold for more than $30.000
