Dutch, Customs Seal, 290, Image & Found by Old Man.
Found within a 3 mile radius of Colyton in Devon, 19mm diam., 13.2g.
This seal is an animal tail tag customs seal. The rivet appears to display a portion of the crowned Dutch shield bearing the rampant lion of Holland. The other side has the number 290 with C that could be from ACC below. There appears to be a quantity of animal hair remaining trapped by the rivet between the discs.
From Jan van Oostveen, "It was only used for the tail and not for the ear. ... from authentic documentation from the mid-19th century where it is mentioned how these seals were used. [Scheffer, D.H., 1909. De Geslachtswet. Amsterdam.]" See Oostveen, J. van, 2019, Tax seals used in The Netherlands as proof that 'accijns op het geslacht' was paid.
