This reflects an obsolete method of die preparation, as new designs introduced since 1907 have had their inscriptions sculpted into the artist's model rather than punched into the master die. 

He may mean after 1867, that was about the time the mint got its first portrait lathe which allowed master hubs to be made from full models.

The Philadelphia Mint acquired its first portrait lathe in 1835 and an improved model in 1861. Nonetheless, the old-school engravers such as Longacre, Morgan and the two Barbers continued to punch lettering into the master die, rather than sculpting them. The dates and mintmarks were punched into the working dies. In the case of the 1900 Lafayette Dollar, Charles Barber didn't even create a master die. He punched the legends into each of several working dies, and the coins are thus collectible by dies.
