One scoped currency identity. Changes to subdivisions, scale, standard, instruments or issuers do not by themselves create children. A distinct account unit can remain a successor. Dated observations: AD 780–AD 805; this does not establish the entire lifetime.

Earlier account evidence
A reported780 price comparison values a bolt of plain silk at4000 cash and a dou of rice at200 cash. These show money-denominated prices; context does not warrant universal purchasing-power estimates.
Lu Zhi’s memorial against the twice-yearly tax describes conversion of different property categories into strings of money for assessment. This directly establishes fiscal account valuation independently of settlement material.
Scoped Tang monetary accounting in cash and strings: fiscal valuation and prices, not a separate node for each coin inscription. No claim yet about continuity from earlier dynasties or into every Song region.
The museum distinguishes Chinese coin models, medieval one-coin/one-mon reckoning, and independent Edo gold, silver and copper values. This does not by itself establish Tang-account to Japanese-mon ancestry or merge mon, ryō and silver monme.
Qin cash obligations establish an earlier Chinese account witness. The reviewed ordinance does not establish the intervening account continuity through Han and Sui to the Tang profile.
Dated evidence, not exact birth or extinction dates.
