Rice Krispie Treat Pin

[magicbob]

One of the pins I recently traded for is a Mickey Rice Krispie Treat. The portion that is chocolate covered has a smooth edge, but the bottom 2/3 of the pin has an almost serrated edge. It looks like this is intentional to simulate the texture of a rice krispie treat. Is that how the pins are made? The reason I ask is that I read here that rough edges often indicates that the pin is a "scrapper." But in this case, I think maybe the edge is supposed to be that way. Does anyone know for sure? Thanks.
