Question: acnl what to do with superb coffee beans?
Answer: You do also get a coffee maker from Brewster, but it is purely for decoration. All of the beans can be sold for up to four times more (minus one) via the flea market than to Reese - for example, the superb beans fetch 2000 with Reese and up to 7999 on the flea market. They are useless unless you sell them.
