For deeper research, Eric P. Newman’s The 1776 Continental Currency Coinage & Varieties of the Fugio Cent is the definitive source of information on the pieces, but the latest edition of this particular work dates to 1982 and provides only black and white photos.
In contrast, the Whitman Encyclopedia of Colonial and Early American Coins, by Q. David Bowers, published in 2009, provides full-color illustrations of the coins.
If Mr. Roberts is still undecided on the probable authenticity of the piece, he might consider attending a large coin show where reputable certification services are on hand who can examine the piece and offer an opinion.
