Matrix (numismatics) 2762237 223901236 2008-07-06T12:23:08Z Lightbot 7178666 Units/dates/other {{otheruses3|Matrix}} In [[numismatics]], a '''matrix''' is an intermediate used in the process of manufacturing [[coin]]s. A matrix has its design in the same sense as a [[Die (manufacturing)|die]]. The design is engraved convex into the matrix, which is used to create [[punch (numismatics)|punches]]. The matrix step was developed in the 17th century for two main reasons. The original design in the matrix could be better preserved, as a single matrix could be used to make several punches. Second, it made easier the addition of secondary details such as the legend, a difficult task on a punch, which is in [[cameo]]. [[Category:Numismatics]] {{coin-stub}}
