The first American edition has an A and the Scribner colophon on the copyright page. First issue dust jacket has yellow spine lettering (later issue jackets have orange spine lettering.)
The British edition published by Jonathan Cape is said to have preceded the American edition by a few days, but the American edition published by Scribner's seems to be just as desirable, especially the one with the yellow letters on the spine. This is probably because Hemingway is an American author and the Scribner's was his traditional publisher.
There were also 25 Scribner's presentation copies that preceded all other editions (see last photo).
