[2][3] The Schüsselpfennig was widespread and can even be found in dictionaries described as a "small one-sided pfennig made of silver with a rim that is curved upwards like a dish".
The convex shape of the pfennigs proved to be very practical in payment transactions because the small coins were easier to grip than their flat counterparts.
From the 15th century, its characteristic feature was its curved shape and the thick beaded circle that surrounded the coin image.
[6][7] In Electorate of Saxony, low-value Schüsselpfennigs made by the various mint lords, for example of Nassau-Holzappel, Solms-Hohensolms or [[House of Leiningen#Leiningen-Westernburg|]], became known as "invaders".
They already have the typical bowl or saucer shape with a pearl circle surrounding the coin design (see the Strasbourg Lilienpfennig).
The Schüsselpfennigs that followed later had a characteristic thick pearl circle that gradually became less noticeable or disappeared in later coins from the 16th to the 18th century.
