The meaning of "dumb romantic guinea"

[Dmitry A. Kovalsiy]

Hi everyone!

I've just started to read "The Godfather" and faced with unclear phrase. This is a peace of the text in order to understand the context:

Johnny Fontane got up. He hated the woman on the floor but her beauty was a magicshield. Margot rolled away, and in a dancer's spring was on her feet facing him. Shewent into a childish mocking dance and chanted, “Johnny never hurt me, Johnny neverhurt me.” Then almost sadly with grave beauty she said, “You poor silly bastard, givingme cramps like a kid. Ah, Johnny, you always will be a dumb romantic guinea, you evenmake love like a kid. You still think screwing is really like those dopey songs you used tosing."...

What does "romantic guinea" mean? I understood it sounds offensive and with contempt.
I do know a guinea can refer whether to the African country or coin. What about another meanings?

Thank you in advance

In the time in which the novel is set, Guinea was an offensive term in American English for an Italian-American. Romantic is an adjective which you can look up in a dictionary.
