My 1972 Chemical Engineering diploma from the University of Tennessee is on sheepskin.
The University of Tennessee did issue sheepskin diplomas historically, with at least one confirmed example from the late 19th century.
Today, however, the University of Tennessee, Knoxville (UTK) issues diplomas on paper, not sheepskin. Current UTK diplomas are produced in specific standard sizes on quality paper.
Historically, many institutions, including the University of Tennessee, originally produced diplomas handwritten on thin sheepskin (parchment). This practice generally ended about 100 years ago when institutions began using parchment paper and standardizing sizes.
Is it possible that you actually graduated in 1872 instead of 1972???
Harvard University stopped issuing sheepskin diplomas around 200 years ago.
