Letters between Granvelle, at that time in Madrid, and his secretary Morillon in Brussels show that Jacques Jonghelinck, master medal maker with a workshop in one of the buildings of the palace complex in Brussels, in the spring of 1566 had made a mould for a small medal. Successively he cast medals in lead, tin, copper, silver or gold (specimens in tin or copper now are unknown; a very few specimens in lead are found, but because lead is inherently soft - so the medal is not "stable", its eyelet is of questionable authenticity - lacking proof that they are real originals and not later date copies). On June 15 Morillon sent a lead specimen to Granvelle with the sneer that more medals were cast in lead then in the other metals; a medal for poor people "affin peult-estre gue les Geutz demeurent en leur qualité", something like 'perhaps the quality (of the medals) being in line with the standing of the Geuzen'.
