How much is Tapa worth?

Tweet

I have a piece of tapa cloth (mulberry tree bark beaten to make a fabric-common in the South Pacific/Pacific Rim) and I am thinking of selling. I have looked online but cannot seem to find the actual value of tapa. I hear that it is rare and the piece I have is in excellent condition and stamped with MUSEUM QUALITY. I have no idea how much to sell it for. Does anybody know how much tapa is worth?
