Etymology
貝 is a pictograph of a shellfish with its shell and soft body. The modern form retains the shell-like shape with a closed top and dangling lower parts.
Meaning mnemonic
The top box is the hard shell, and the two strokes below are the soft body peeking out. Picture a clam opening slightly: 貝 is a shellfish.
Reading mnemonic
For バイ, imagine buying a shellfish at the market: buy -> バイ, and you get a fresh clam.
