I know @Amandq made one of these a while ago, but I feel it necessary to make another one as some prices have been changing. Lets get started with the Passive Mob Spawners Chicken: 275k - 325k Cow: 275k - 325k Sheep: 275k - 325k Rabbit: 275k - 325k Pig: 275k - 325k (Notice the trend with passive mobs?) Next, we move on to the ones mainly used for XP Farms Zombie: 700k - 850k Skeleton: 700k - 850k Witch: 475k - 600k Spider: 700k-850k Zombie Pigman: 800k - 950k Slime: 900k - 1m Blaze: 1m-1.5m These ones are based upon a combination of their rarity and their usefulness. Finally, onto the 3 best spawners on skyblock. The Money Makers Creeper: 1m - 1.5m Enderman 1m - 1.5m Iron Golem 30m - 35m Don't let someone overprice you on an IG (Iron Golem Spawner) as it often happens because the majority of players keep raising the prices up. Moving on to some other Holy Crate Items Legendary Sword: 300k Legendary Chestpiece: 300k Legendary Leggings: 300k Legendary Helmet: 250k Legendary Boots: 250k Villager eggs: 10k per egg Harvester Hoe: 10k Sell Wands (1500 uses): 10k Legendary Shovel: 250k Legendary Pickaxe: 250k Legendary Axe: 250k Diamond (Axe, Pickaxe, and Shovel): 100k Mythical Pickaxe: 200k Godly Pickaxe: 150k Epic Diamond Pickaxe: 125k All of these are based on how common they are and what their special perk is. Moving on to Music Discs All 12 of them: 2.5k each (30k total) I have a shop on my island where i sell them for this price. Heads! /headgrabber is an infinitely usable command from the store, so heads are cheap. Any head: $0 - $100 I want to end with one of the most overpriced things on Skyblock right now, Keys There are many, MANY different perspectives on what keys should be sold for, but sadly, a large majority of them are just simply too much money. I've seen people offer upwards of 2m per key before, it's ridiculous. Let's put something into perspective. The crate rewards are weighted. You have a higher chance of getting something not as rare. 39/44 items from the Holy Crate cost less than 1m. If you purchase a key for 1m, without any weighted systems you already have a 5/44 chance to get something worth 1m+. That's a low chance by itself, an 11.4% chance. But that's not the case, otherwise Iron Golems spawners would be flooding the market (literally). It's weighted so you have a lower chance to get the higher items. The best price for keys would, by making the most sense out of any price I've seen, be 250k - 400k per key. This is the price I offer in every trade because it is MUCH more fair than 1m - 2m a key. I hope you all find this useful moving forwards when doing a trade for anything on this list.
