=== Shield ===
On October 28, 1926, the trustees approved a "Dartmouth College Shield" for general use. Artist and engraver W. Parke Johnson designed this emblem on the basis of the shield that is depicted at the center of the original seal. This design does not survive. On June 9, 1944, the trustees approved another [[coat of arms]] based on the shield part of the seal, this one by Canadian artist and designer [[Thoreau MacDonald]]. That design was used widely and, like Dwiggins' seal, had its date changed from "1770" to "1769" around 1958.<ref name="good"/> That version continues to be used under trademark registration number 3112676 and others.<ref name="uspatent"/>

College designer John Scotford made a stylized version of the shield during the 1960s, but it did not see the success of MacDonald's design.<ref name="A Proposal for a Heraldic Coat of Arms for Dartmouth College"/> The shield appears to have been used as the basis of the shield of the [[Geisel School of Medicine]], and it has been reproduced in sizes as small as 20 micrometers across.<ref name="Nanometer Pattern Generation System: Dartmouth Seal"/> The design has appeared on [[Rudolph Ruzicka]]'s Bicentennial Medal ([[Philadelphia Mint]], 1969) and elsewhere.
