Yadav, who continues to occupy the same seat in the front rows of opposition benches as he did before his party forged an alliance with the BJP in Bihar, showed enlarged copies of differently sized 500 rupee notes.
"I can give signed copies" of the notes, he said as treasury benches countered his contention which was earlier raised by Kapil Sibal of the Congress.
Yadav has been maintaining a studied silence on Bihar Chief Minister Nitish Kumar breaking alliance with Lalu Yadav's RJD and Congress to form a government with the BJP.
He continues to sit with BSP's Satish Misra on one side and SP's Ramgopal Yadav on the other. Also occupying the front row is Sitaram Yechury of CPI(M).
