What book involved forging one of the United States' founding documents?

Question

A few details of this book that I remember include:

• A specific type of parchment was purchased to forge either the Constitution or Declaration of Independence. This parchment was old enough to fool carbon dating.
• A man urgently needed money for a bus ticket and traded his expensive watch for that money.
• There might have been some type of plastic surgery on someone's face to change his or her identity.
• I think this was set in either the United States or another English speaking country like England.
• I think there was a part with a woman on a train or a bus who was being sexually harassed by some (possibly British) men who said something along the lines of "I like black birds".
• I read this around 9 years ago and at the time thought it was a very well-known book.

I have been wondering what this was called for years and I would appreciate it if someone could figure it out.

Answer 1

Perhaps "Honour Amongst Thieves" by Jeffrey Archer.

• "But the toughest requirement proved to be the parchment itself, because Dollar Bill wouldn't consider anything that was less than two hundred years old. He tried to explain to Angelo about carbon dating."
• "If you can't pay, you've gotta debus 'cause that's what the regulations say." "'I'll give you a dollar for that watch,' said a young man seated in the second row who'd been enjoying the confrontation."
• 'My friend Marv fancies you. Did you know that, Sloane?' Hannah smiled at him as she began planning the route she would have to take out of the carriage once the train pulled in to the next station. 'Quite like you myself,' he said. 'But I prefer black birds.'
