Hello, Yes, you are correct with mine, and sell, but there are other useful tips in Prisons. For me, I would mine until I could get round 5million dollars, until then, you should get around 30-50 tokens, (depending on what armor pieces, Token of Luck enchantment, etc). Also, instead of selling the ores are the normal mine, you could sell them at an ore sell shop. My personal favorite is /p h zakprofit. Another good plan to get a large assumption of money, is to make an automatic spawner farm, that kills the mobs automatically and it automatically picks it up for you. This could also give you are big advantage. With the spawner farm, it is very hard to start one, but once you get rolling, the money gets easier and easier to get. I hope all of these tips helped someone! Have a nice day, -ObjectiveArcade
