A simple coin with a smiley face on it.

These coins once helped my son express his inner feelings to us at any time.
I call them "emotional coins".
Previously, therapists just used an emotional chart to assist in communication.

The back of the coin is designed with a flat bottom surface.

The design was made using Tinkercad.
