Federal Reserve Notes are not dollars.” Russell L. Munk, Assistant General Counsel, Department of the Treasury, February 18, 1977.
“The term ‘dollars’ likewise is incorrect, which, according to constitutional definition, are monetary units, used in exchange, backed by gold and silver. Our present day fiat issues are supported by more printed paper of the same; therefore, they are correctly termed Federal Reserve Notes (FRN), not dollars. Robert P. Vichas, Handbook of Financial Mathematics, Formulas, and Tables (1979), p. 420.
