Watch List notes:

FRENCH INDOCHINA: AR piastre, 1922-H, KM-5a.3, with two inverted rectangular chopmarks reading yong kim hong in Thai, old cleaning, Fine. This chopmark, possibly made by a Sino-Thai merchant whose chopmarks are also known to be in Chinese, is considered by some as a fantasy applied in the mid-20th century.
