The whoopee is now outdated and needs a mini, and a ~1 week unsold at 72 on classifieds indicates that it needs a drop. You should try making a mini on it, or even better a full suggestion.

Although while we're at it, looks like a duped one sold for a Burning Demoman's Fro(the crown added 10 keys)

If the fro has no sales then this could be supportive at least, though i'd expect this sale to set the high end for this.
