selling pawn items is DISCOURAGED on Windlyn, that is why they are only worth 1 feather. (Versus fishing pond items being worth full value to sell to the pawn shop)
If you DON'T want even items there are members who will buy them or trade them for you. (Check out my barter town thread if you want to trade).
For this event you are better off redeeming the gems for items and then putting them in your personal shop later or trading some others who miss the event for past items, or starting your own charity thread.
