Ok...you guys took my comment far too seriously, My point was that I do not need to have a name or rare piece to cook with, almost all of my cookware is older unmarked iron with the exception of maybe 1 or 2 older Wagner pieces, When I look for iron that I am going to keep I always look at the smoothness of the cooking surface and the wall thickness, Smoother and thinner is better in my opinion for cooking than thicker and rough.
My idea of abuse is general usage and not being displayed on a wall or rack
If I can find a nice piece that has some collector value to someone and I can make a little money on it and someone gets a piece for their collection I am happy and with the money I can add to my mostly unmarked set that I have just to use in the kitchen.
