I'd say the greedy, big nosed, big eared Ferengi and the greedy, big nosed and big eared flying merchant from Star Wars I.
I assume it's no direct plagiarism, but in both cases the character designers where influenced by the same antisemite stereotypes:
Gerald Krefetz summarizes the myth as "[Jews] control the banks, the money supply, the economy, and businesses—of the community, of the country, of the world".[66] Krefetz gives, as illustrations, many slurs and proverbs (in several different languages) which suggest that Jews are stingy, or greedy, or miserly, or aggressive bargainers.[67] During the nineteenth century, Jews were described as "scurrilous, stupid, and tight-fisted", but after the Jewish Emancipation and the rise of Jews to the middle- or upper-class in Europe were portrayed as "clever, devious, and manipulative financiers out to dominate [world finances]" (Wikipedia)

As for the imagery - large ears and noses, you should find good examples from Nazi-era propaganda posters, maybe I'll add some after a search later.
Note that I'm not saying that in both cases the character designers were intentionally hateful antisemites, but I think it's fair to say that they used visual and other tropes also very present in modern antisemitism.
