Easy way to remove collars from GeoTIFF of USGS Topo?

I have downloaded a lot of GeoTiffs of historical topo maps from the USGS ( at the 1:24000 scale. I am wanting to Mosaic these together to eventually clip to watershed boundaries, however the white collars on the outside are proving to be a headache. I have not been able to find a solid answer on these forums or anywhere else on the internet of how exactly to remove the collars. 


Does anyone have an answer?


Any help would be appreciated!
