everyone has their own local fruit, it is assigned randomly when you first start playing the game. local fruits are lychees, grapes and limes/lemons. in my case, my local fruit is lemons (my trees don’t grow lychees or grapes) and i can sell lemons them from my inventory for 10$ just like any other regular fruit. but when i buy lychees or grapes from my friends’ market, i can sell them for a higher price (600$) directly from my inventory... same happens to you, if you happen to buy lemons from your friends market you can sell them for 600$ from your inventory so that’s a good strategy to gain a lot more of bells. there’s also perfect lychees, grapes and lemons... in your case you can sell your perfect lychees for 600$ but if you buy perfect lemons or perfect grapes you can sell them for 3000$ lol sorry for the long post
