I think it would be interesting/informative to have approximated suggested retail prices at the time of release. That, I would like. eg. $20 (1984)
If the prices noted are an estimate of current "value", then I would prefer that they not be in there.
But, it wouldn't matter much to me if they were there or not -- I'd still buy the books. Maybe a few sets. One to look through, and another to keep in minty condition.
