"Nearly all of the 1,427 coins, dating from 1847 to 1894, are in uncirculated, mint condition," said Kagin told ABCNews.com.
He said that the couple plan to sell most of the coins, but before they do, they are "loaning some to the American Numismatic Association for its National Money Show, which opens Thursday in Atlanta."
"Some of the rarest coins could fetch as much as $1 million apiece," said Kagin. He also said that they wish to sell 90 percent of the collection through Amazon.com and on the company's website.
"We'd like to help other people with some of this money. There are people in our community who are hungry and don't have enough to eat. We'll also donate to the arts and other overlooked causes. In a way it has been good to have time between finding the coins and being able to sell them in order to prepare and adjust. It's given us an opportunity to think about how to give back," said the couple.
Kagin and his colleague David McCarthy, senior numismatist and researcher at Kagin's, met with the couple last April, two months after the hoard was found.
When McCarthy and Kagin told the couple that their bonanza will be in the annals of numismatic stories for quite some time, the couple said, "It would have been quite a pity not to share the magnitude of our find. We want to keep the story of these coins intact for posterity."
