Att: The Fractional Coin of Laos, Siam, and Cambodia

Illustrated Specimen Details: Kingdom of Laos 10 Att

Example Specimen: Aluminum 10 Att (10 Cents), 1952 (Kingdom of Laos)

Iconography & Origin: This aluminum coin was struck in 1952 under the authority of King Sisavang Vong, who ruled the Kingdom of Luang Prabang and later the unified Kingdom of Laos from 1904-1959. The design features a central hole surrounded by a stylized plant ornament. The inscriptions include ROYAUME DU LAOS in French and ພະຣາຊະອານาຈັກລາວ in Lao script, alongside the Lao Buddhist Era date ໑໑໕໒ (1952). The obverse displays a symbolic portrait of a Laotian ethnic woman with a traditional braided bun hairstyle, representing the Lao Loum (Lowland Lao) nationality. It bears the official marks of the Paris Mint (Monnaie de Paris): a cornucopia for the mint and a wing for the chief engraver Lucien Georges Bazor.

Monetary Context: The denomination on this transitional issue uses a double standard, inscribed as both "10 CENTS" and "໑໐ ອັດ" (10 att). At the time of minting, the French Indochinese piastre (equal to 100 cents) was still the official currency of the territory. This coin represents the crucial transitional monetary period from the colonial piastre and cent to the independent national kip and att.

1. LAOS (Kingdom and Lao PDR, 1952-present): att = 1/100 kip
2. KINGDOM OF SIAM (1862-1905): att = 2 solot = 1/2 pai = 1/8 fueang = 1/16 salung = 1/64 baht
3. KINGDOM OF CAMBODIA (19th century): att = 1/2 pe = 1/8 fuang = 1/64 tical

About the name: The name of the coin "att" (Thai: อัฐ, Lao: ອັດ) is derived from the ancient Sanskrit word "अष्त" (aṣṭá or aṭṭha), which translates to "eight". This linguistic root reflects the historical structure of the currency; when the first Siamese att pieces were introduced into marketplace circulation, they were valued at exactly 1/8 of a fueang.

The Evolution of the Att in Southeast Asian Numismatics

The att (alternatively spelled "at") represents a historical small-value fractional denomination that played an important role in the monetary history of mainland Southeast Asia. It was utilized across the historical trade networks of Thailand (Siam), Laos, and Cambodia, adapting over centuries from traditional regional structures to modern decimal frameworks.

Regional Implementations and Standards

Before the widespread monetary modernization of the late 19th and 20th centuries, regional systems relied heavily on traditional accounting models influenced by Indian silver-weight standards. The att functioned differently within each sovereign nation:

• Siam (Thailand): From 1862-1905, the att was an integral component of the non-decimal system where 64 att pieces equaled 1 standard silver baht. It was subdivided further into smaller copper units, notably being worth 2 solot or half of a pai.
• Cambodia: During the 19th century, Cambodia maintained a highly parallel monetary system linked to Siamese traditions, where 1 att was valued at half a pe or 1/64 of a tical currency unit.
• Laos: Beginning with the transitional issues of 1952 and continuing into the modern Lao People's Democratic Republic, the denomination successfully transitioned into a clean decimal standard, with 1 att defined exactly as 1/100 of a Lao kip.

Linguistic and Production Characteristics

Numismatists note that historical references to these systems often contain variant spellings based on localization transliterations. For example, in Siamese accounting, the denomination immediately above the att is properly transliterated as fueang (though often simplified to "fuang" in older European catalogs).

Physically, the att manifested in incredibly diverse formats over time. It evolved from traditional Siamese silver and copper bullet money (pod duang) and locally cast or struck copper tokens into sophisticated, machine-struck decimal elements manufactured at prestigious institutions like the Monnaie de Paris. Common design features across these regions frequently combined royal emblems, sacred elephants, the multi-weapon chakra wheels, and local scripts.

Key Point

The att was a small-scale Southeast Asian marketplace currency denomination. Originally established as a non-decimal fraction representing 1/64 of a silver baht or tical weight standard, it ultimately transformed into a modern decimal subdivision representing 1/100 of the national Lao kip.
