Hello Nora.
We have a trophy and the winner's name is engraved on it.
Given the 'politics' that seem to surround allotment committees, I think it would not be a good idea, as chair, to make a decision to retire it. It would probably be best to continue it for this year and let a decision be made by the association members at the AGM as to whether they want to continue it. Beauty is in the eye of the beholder!
