Chashivos

The gemorah on 47a mentions that a pan that had dirt in it may be Muktzeh if it wasnt for the fact that it still has a small peice of incense in it. The Gemorah then asks that is a small peice of incense worth anything to Rebbi who was quite a wealthy man? My question is what do we do with the concept that we learn from Yaakov and the pachim ketanim? Anything even how minor it may be should should be worth somethig to him? Not much of a question but just a thought!!
