The kanji 売 is a 形声文字 (keisei moji), a phono-semantic compound. It is composed of two parts: The top component is 亠 (dot), and the bottom part is 貝 (かい - shell/currency). 貝 (かい) represents currency or money, and the dot is a symbol that represents a 'vessel' or container that the value of money is stored. Together, they represent an exchange with money. Therefore, 売 came to mean to sell, or exchange goods for money.
