Originally a lordship, elevated to an immediate fief in 1498 and to a county in 1586. Its core lies in present-day Eijsden
(Limburg, Netherlands). Coinage was issued by the lords and later counts of Gronsveld. Minting began under Jan II of Gronsveld
(c.1375–1386) but became prolific under the Bronkhorst-Batenburg line.
