How much amount I will get for my gsec?

I have one doubt.
If my Gsec bond is trading at 103 at the time expire.
let say my gsec bond will expire tomorrow.
will I get the trading price(103) or the issue price (100)?

You will receive 103 (in your trading account) if you sell it on the secondary market
(NSE/BSE wherever it is trading at a premium).

You will receive 100 (in the linked bank account) if you let it expire/mature.

how to find the issue price of the bond?
Thanks in advance :sunny:

Issue price is irrelevant. Gsec will be redeemed at face value.
