Old hat cosmetic

I usually pay attention to the small details and copy skeleton ouffits that I see in the tall tales and I have noticed that several skeletons use the object that can be fished as treacherous loot "old hat" and sadly it is not possible, currently there is an achievement that you have to use you have to sell 50 treacherous objects and as part of that idea I could make it so that by fishing or selling "X" hat to old men you can obtain it or buy it or unlock it automatically. In the cosmetic chest it could also be an expensive cosmetic or Simply cost very little between 10-30 of gold, but that recommendation is difficult.
