What are the two phases which the moon appears as only a tiny silver?

The two phases during which the moon appears as only a tiny silver crescent are the New Moon and the Waxing Crescent phases. During the New Moon, the moon is positioned between the Earth and the Sun, making it nearly invisible. As it moves into the Waxing Crescent phase, a small sliver of the moon becomes illuminated, creating the characteristic crescent shape. This crescent reflects sunlight and is visible in the western sky shortly after sunset.
