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". 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. 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.
