There are several badges related to having an accepted answer (Scholar, Enlightened, Guru) but none that relate to achieving a certain threshold of accepted answers. For example, knowing somebody has had 10/50/100 answers accepted would increase my confidence that they know what they're talking about (not just throwing out lots of mildly helpful answers over time), and is yet another way to reward people who provide an excellent answer.
Here are a few name ideas such badges...
In speaking with the SO team about this earlier, they suggested that "there's a 'rich get richer' problem with this style of award." I can see how that can certainly happen, but I see it in a different way...
People who strive to provide good answers in less-popular tags (such as Cocoa and Objective-C, like I do) will likely never get enough votes/views/favorites to earn most of the popularity-related badges. In contrast, an "N accepted answers" badge can be earned through technical knowledge and helpfulness, without being tied to a popular technology. (Or posting a subjective/controversial/funny question/answer, whether intentionally or not.)
Of course, if knowledgeable people start answering every question just to "level up" on accepted answers, I can see how newer members can feel left out. However, I (like to) think most people aren't prone to abuse the system that way, and more good answers does benefit the community as a whole.
