Netherlands. Wilhelmina. 10 Cents 1898 & 1901 "Inhuldigingsportret met diadeem" (2 opeenvolgende) (No reserve price)

These two consecutive 10-cent coins from 1898 and 1901 depict Queen Wilhelmina with the "Inhuldigingsportret met diadeem," or inauguration portrait wearing a diadem. This design marks a formal, regal representation distinct from her youthful portraits, underscoring important milestones during her reign. The inclusion of a diadem symbolizes royal authority and ceremonial significance. Such coins hold numismatic importance due to the commemorative nature of the design and the subtle shifts in portraiture that reflect the maturity of the queen’s image in national coinage. They are prized by collectors of royal-themed coins and early 20th-century Dutch monetary issues.
