Gold Coins can be earned by selling crops from your garden. If you ever run out of Gold Coins, remember you can sell the apples that grow on the tree!
To sell your crops, select the market button in the bottom right corner when looking at the garden. You’ll be able to scroll through all the crops you own and choose how many you would like to sell. The amount of Gold Coins you get for selling is shown on the right side, and the total Gold Coins you’ll get from selling multiple crops is displayed at the bottom.
