Mosaic DEM Problem

I am wanting to mosaic many DEM Grids into one large DEM Mosaic. They do NOT overlap and they appear to be perfectly adjascent to one another. When I mosaic them, everything appears to turn out well. However, when I run a hillshade, you can notice a distinct seam/line where the tiles met. This is a problem because it is affecting further processing on the mosaic DEM (ex/ Hydrology, Flow Direction etc...).

Is there a way to create a trully seamless mosaic? Perhaps there is a way to interpolate the seam area? Perhaps I should be using another tool (merge)?

Any help would be appreciated.
