The scrapped currency in the denomination of Rs 1000 and Rs 500 was deposited by lakhs of devotees in the hundi or the offering box.
It was deposited a few months after the centre banned the notes on November 8, 2016.
Keeping in mind the sentiments attached to the cash offerings of devotees, the Tirumala Tirupati Devasthanams has written letters to RBI for exchanging the currency, said Additional Financial Adviser and Chief Account Officer O Balaji of Tirumala Tirupati Devasthanams that administers the hill temple.
They were awaiting a "positive reply," he said.
The scrapped cash stockpile has been kept safely at the temple itself, he added.
