By Greg Reynolds for CoinLink - An 1870-CC Double Eagle ($20 gold coin) is 'again in the news' as one will be auctioned by B&M during the evening of Friday, Nov. 21st, at the Baltimore Convention Center. It is graded "EF-45" by the Numismatic Guaranty Corp. (NGC). It is certainly the same 1870-CC Double Eagle that was sold by Stack's on January 16, 2008 in New York, at which time it was not certified.
