Hello Skyblock, I had an idea to get grass, so I started auctioning a nether wart. I said people could bid anything, one person bid one air, another bid 2 air, then someone bid 5 cookies. The craziest bid was 1 grass. Someone then did 2 grass, the same person who bid 1 grass now bid 3 grass. So I sold my nether wart for 3 grass. Next, I sold a spider eye for diamond pickaxe with some good enchantments. This may be a joke but people do actually bid on dumb auctions.
Ok...? You might be able to sell some kind of stuff for higher by auctioning it rather than selling it.
I would do it mainly to give poorer people some more money, oh and because if you give them anything more than 10 grass they go absolutely crazy and its kinda funny...
1 grass is a high bid? I remember someone bidding 50 grass for 1 diamond back in the good ol days of .net
