I have tested the market on the supposedly rare commons and though some are more difficult then others, there is not really a rare common if you are strictly considering the front of the card. I have the Lundgren with the PD350 back and that to me would be a good example of a rare common.

The others that are considered "tough" are usually Tenney, Ganley, Ames(hac) and then the team variations for Lundgren, Browne, Dahlen, Elberfeld, Smith and Kleinow. Dahlen seems to be gaining some ground in price but you could pick any one of these up with a little cash and a trip to ebay.

The SLers are a different group to discuss but again with some money, they are pretty easily obtained.

I tend to like "tough" when describing cards in this set. Some are tougher.
