In Derby, Coffee made busts of some of the local people and historic figures including a life size sculpture of Erasmus Darwin. This bust is a good example of Coffee's modelling skills and is now on show at Derby Museum. Coffee also produced a terra cotta copy of the Florentine Boar (1806) and a number of terra cotta statues of Greek figures showing medicine and healing for the garden of Joseph Strutt. The garden was given to the town as Derby Arboretum in 1840 complete with statues, but those of the Greek figures are now missing or lost. Coffee also made a terra cotta statue of Asclepius for William Strutt's Derbyshire Infirmary, opened 1810.
