1748 tr. N. A. Pluche Spectacle de la Nature VII. xxiii. 284 The Planchet of Metal was horizontally laid upon this inferior Mass, to receive the Stamp of it on one Side, and that of the upper Die, wherewith it was covered, on the other.

1788 tr. J. von Stæhlin Orig. Anecd. Peter the Great xv. 60 A die was placed upon the place, a planchet laid upon it, and the bar put in motion.

1794 P. Wakefield Mental Improv. (1801) I. 136 To cut out as many planchets or circular pieces of metal.

1847 Debow's Rev. June 534 Each operating press requires a man..to keep a vertical brass tube supplied with the blanks or planchets to be coined.

1856 Sci. Amer. July 368/1 The planchet being pushed to its dish, is counterpoised by a just weight on the opposite dish; if the planchet is right, there is little or no oscillation.

1879 H. Phillips Addit. Notes upon Coins 8 In many instances the coin contained only a portion of the device, the rest having failed to reach the planchet.

1965 K. Skov tr. J. Brøndsted Vikings x. 190 It was probably German influence which produced coins of the same weight as before but on a larger and thinner planchet and, therefore, more crudely stamped.

1992 Numismatist Mar. 360/3 Coins were produced in regular presses and with a single blow, but using polished planchets.
