If you can clean it up and get a good buyer, I'd say about $30 profit
May be this is possible, but will not be fast and easy. I think that SE SS Delica is a least popular variant of Delicas, due to the weight, edge configuration and slippery of the handle. So it can take a long time to find a buyer, who will be willing to shell-out $50 + shipping for used SS SE Delica, especially considering that you can get off e-bay PE FRN for the same mid fifties. CE even for less.
