Iran: inherited accounts and an adopted Indian basis

The Persian toman–dinar profile now includes a qualified association with Ilkhanid fiscal accounting in 1335 and a regional kepaki-toman payment in 1506. Firm descriptions of toman accounting in 1626 and 1637 precede the previously recorded 1651–1652 witness. Scholarship explicitly describes inherited money of account through the intervening dynasties; regional differences remain visible.

S1039 · S1040 · S1038

In 1740 Nader Shah deliberately aligned Iranian rupee/naderi reckoning with Indian rupees: one Iranian silver toman was set equal to 20 silver rupees. This is recorded as a qualified unit-adoption step-parent. It preserves Iranian ancestry and does not assert an enduring market peg. Inspect the decree reports, implementation and limits →

India: the rupee reaches Mughal accounts

A new Mughal rupee–dam account profile is grounded in the Ain-i-Akbari’s salaries, duties and accounting rules. It distinguishes the fixed salary reckoning of 40 dams per rupee from market exchange rates. The textual witness is dated conservatively to the 1590s. Sher Khan’s earlier rupee is profile context; minting and dynastic changes do not create extra nodes.

S1041 · S1042 · S1043

The Mughal profile connects to Calcutta sicca through qualified Bengal and Nawabi regional stages. This extends the existing path onward to the Indian rupee and its descendants while preserving the separate Patna and current-rupee account questions.

China: peso-derived yuan, distinct taels and Qin evidence

Von Glahn explicitly identifies the yuan as a money of account derived from the Spanish peso. A qualified ancestry link now records that inheritance through regional dollar systems and later national consolidation. The existing yuan profile extends to a firm 1910 account witness; it does not absorb every eighteenth-century local dollar standard.

S1044 · S1045

The Shanghai tael now has an 1857 account observation and the Haikwan customs tael an 1880 contemporary witness. These remain distinct profiles. A new Qin cash (qian) fiscal account is grounded in an excavated ordinance concerning cash obligations and loans, dated approximately to 221 BCE or shortly afterward. Its connection through Han and Sui to Tang accounting remains open.

S1044 · S1046 · S1048

Japan and Korea: boundaries retained

Chinese coin models and imported coins do not yet establish Tang-account ancestry for Japanese mon. The reviewed source also distinguishes Edo gold, silver and copper accounts, so ryō, mon and silver monme remain separate. Korea’s earlier silver won/nyang and the 1905 yen-based reform need a coherent identity review before another ancestry edge is added. The four retained Korean profiles now appear in East Asian navigation; that move does not change their ancestry.

New relationships

Mughal rupee–dam accounting → Calcutta sicca rupee

Bengal and Company sicca accounting inherited the Mughal rupee system through regional Nawabi arrangements. Admit compressed regional ancestry, retaining distinctions among sicca, current and Patna accounts. The immediate stages and differentiation dates remain qualified.

Spanish real / peso de a ocho → Chinese yuan — late Qing and ROC mainland continuity

Chinese yuan money of account developed from Spanish-peso reckoning through regional dollar traditions, later Mexican-dollar predominance and national consolidation. Admit compressed inherited ancestry, not uniform eighteenth-century national currency or a perpetual peso peg.

Mughal rupee–dam accounting → Persian toman–dinar accounting — Ilkhanid and later traditions

Nader Shah’s implemented 1740 reform deliberately aligned Iranian rupee/naderi reckoning with Indian rupees and set one silver toman equal to 20 silver rupees. Record a qualified unit-adoption event, preserving Iranian ancestry; no continuing market peg is inferred.

S1038

Effect on ancestry depth

21 inherited endpoint codes gain earlier witnesses. The step-parent contributes none of that depth. No Qin-to-modern, daric-to-rial or kahapana-to-rupee chain is asserted.

Extend Persian toman/dinar accounting into its inherited Ilkhanid and post-Ilkhanid tradition. Scholarship explicitly identifies inherited money of account. Earlier regional dinars and tomans retain qualified identity associations; no universal common value across regions is asserted.
