On the contract the amount was written as 'two' in the formal banker's character.
Tips
history
弍 is an old anti-fraud writing of 'two', superseded by 贰 (the standard banker's two used on cheques and contracts today). It is not used independently in modern Chinese; you meet it only in old documents and variant-character notes.
register
Archaic and clerical only. For real-world formal amounts use 贰; 弍 survives only in historical and lexicographic contexts.
The two horizontal strokes are the plain numeral 二, split apart by the inserted bow shape to make the count harder to alter — the whole point of an anti-fraud form.
