How to get money on Animal Crossing: Lets go to the City????

Sell your fruit, things from booker when آپ say you've lost something, plants IF آپ ARE DESPERATE, shells, آپ can also dig up fossils - and when he tells آپ what it is DONT GIVE IT TO HIM, sell it to tom nook. آپ might even find money in trees!and if آپ find items in trees آپ can sell them. hope this helps
