I am curious about this sub set. How many cards are available with the old mill back?

How do they rate compared with the more common backs. I don't see a lot of old mills but there doesn't seem to be a premium on them even though most of the ones I have are either the only or 1 or a few in the population reports. I know for a time the backs were separated, but still they "seem" rather rare.

Any tough cards beyond the SL and HOF.

Thanks
