I first noticed how xp bottles don't sell inside auto-sell chests when I put one inside my massive grinder. The grinder drops rotten flesh, bones, diamonds, emeralds, and several other items, including xp bottles from villagers. However, xp bottles don't sell. Now that mob coins are redeemable by the sell chest, I've come up with a solution to selling xp bottles. The player is expected to take the bottles out of the chest and throw them, breaking the xp out of the bottle. However, this can be tedious when you have to use several bottles. My solution is to give the player a set amount of experience when one bottle is sold. The spoiler below shows how it would work. Spoiler: How It Works For each bottle that is sold, the player gets the set amount of experience times the number of bottles sold. If a bottle contains 10 xp, the player can sell it to earn 10 xp. If the player sells 10 bottles, they will get 100 xp for each bottle. The pros to this are that players have one more item able to be sold and not have to manually collect/click on. This also gives player with villager farms the ability to make it a money, mob coin, and experience grinder in one. The xp would be minimal, but would have a greater effect with higher-level villager spawners, dropping bottles more often. There seem to be few cons with this mechanic, as the xp earned from a normal bottle is so small. I would like to see what you all think!
