Another Q

On May 4, 1536, Francesco Lapi—a Florentine merchant who at the time was in Seville, Spain—used X in a letter, the first ever known instance of a document containing it. Back then, he was referring to the number of "amphoras" that were shipped in three vessels which departed Spain on their way to Rome, Italy. An "amphora" was a commercial volume measure of those times.
What is X?
