The Schulman series was struck by Medallic Art Company in 1971. I cataloged only five of the 12 medals struck. The intent was to have an obverse by one sculptor, and reverse by another (always a bad choice when creating any fine art medal). However, numbers 1, 2, 9 and 10 (Babylonian Market, Croesus, Ben Franklin, David Rittenhouse) were modeled by sculptor Patrick Whitaker, and all reverses by Ramon Gordils. Whitaker could not meet the demand for other medals so these were assigned to hand engravers (uniformity of series just went out the door).
Holly will provide Dick with a copy of the documentation accompanying the medals. Thanks!
