100 Baht Royal Coronation Ceremony of 2019

Issued to mark the formal coronation of Rama X — Vajiralongkorn — which took place in May 2019 after a mourning period of nearly three years following his father's death in October 2016. The coronation itself was the first Thailand had conducted in nearly seven decades, Bhumibol Adulyadej having ascended without a formal ceremony in 1950. That gap made the 2019 event constitutionally and ceremonially significant enough to warrant a dedicated commemorative issue.

Released into circulation in 2020 rather than the coronation year itself, which is common for Thai commemoratives — the Note Printing Works in Bangkok requires lead time for the security feature integration on collector-grade runs.
