If dropped a distance greater than 5 feet, the coin issues a melodious ringing sound when it hits a surface. Any creature that can hear the chime can determine the distance the coin dropped based on the tone.
The Coin of Delving gleams with a tarnished silver hue, its edges etched in faint, spiraling runes that catch the light like veins of ore. When it plummets more than five feet to strike stone or earth, a clear, melodious chime rings out, high and piercing for shallow falls, deepening to a resonant toll for greater depths. Listeners discern the drop's measure from the tone's pitch, as if the coin whispers secrets of the chasm below.
