So I was doing some farming of things like vampires and werewolves and I got rare drops of vampire dust and werewolf fur, and I don't know how many other slayer mobs have rare drops, but I think they should be able to be sold in the market. It would be nice because then it is a nice reward for slaying them as well as less clutter in your chests. I know I could just throw them in the void and get rid of them, but at the same time I feel like it would be a waist to just throw them away. I am playing on the Arcadia server so I don't know if the other servers have sales for them or if others have these drops as well, but I think it would be a nice little addition to add sales to the hoarder shop. They could sell for a fair price and I would like to think of them as selling for higher costs just because of their rarity and low amount that drop, but I could see them even being something cheap just because they are just garbage. The other idea would be make them used for something sort of like how ogre skin can turn gold ore into gold blocks. Do something like the vampire dust can be used to grow a large area of crops like how the grow ability on hoes, but of course make it a little smaller. Or even make it so you can combine 3 of them to make a spawn egg for the corresponding mob. I don't know if this has been brought up before, but I think giving them some sort of use would be really nice to make them actually worth something when they are dropped.
