10 Đồng

The 1980 Vietnamese 10 Đồng belongs to a period of acute economic dysfunction — the unified Socialist Republic was running parallel currency systems in the north and south well into the late 1970s, and the 1978 currency reform that was supposed to resolve this had already failed to arrest inflation. Notes of this series circulated alongside black-market dollar equivalents that rendered official denominations nearly fictitious in practice.

The "Printed: 30.04.1945" field in the source data is almost certainly a cataloging error — that date predates the State Bank of Vietnam's existence by years.
