The original Villager amiibo had a low production run and was in high demand, and thus scarcity was created. Nintendo did finally produce another run of the Villager amiibo, but there are some notable differences between the original and the re-release. This article will help you separate the old from the new.
Although there are differences in the body, it is easier to focus on the head and the face in particular.
As you can see, the eyes of the original Villager are quite a bit bigger than its re-release counterpart. The mouth of the original Villager is also a bit bigger and higher up than on the re-release. But most notable is the position of the nose in relation to the eyes. On the original Villager, the top of the nose is aligned with the bottom of the eyes. This is not the case with the Villager re-release. On the re-release the top of the nose sits in-between the eyes.
The differences are pretty failsafe, so if you have your heart set on a fist run Villager amiibo, the distinct traits mentioned above will most definitely help you out.
