Hi, it is related to the mintage quantities. Only the 1916-D had fewer produced. For 1916, it was only minted in only two of the mints and combined production was a minor 2.3 million. Very small numbers actually.
The reason for the very low mintage of the 1916-D, according to wikipedia, is the need to fulfill a large order of quarters trumped dime production, so they stopped at a minuscule 264K.
