My personal Experience regarding Holding of Gold Bond.
Maximum Senior Citizens Purchase Gold Bond from Bank and keep hard copy in file and we found that lot of time paper misplaced or unable to cash it whenever requirements.

Basically, The customers will be issued Certificate of Holding on the date of issuance of the SGB. Certificate of Holding can be collected from the issuing banks/SHCIL offices/Post Offices/agents or obtained directly from RBI on email, if email address is provided in the application form.
Maximum chances Email Id and paper based bond get damage or misplaced.

My Recommendation
Always open DEMAT Account (Click Here to Open DEMAT Account) and hold all Shares/ Bonds in DEMAT. As its very easy to sale or purchase.

As per the notification issued by SEBI on 8 June 2018, SEBI is aiming for 100% dematerialization of shares within the target date of 5 December 2018. This means all existing physical shares will be required to be converted into dematerialized form on or before 5 December 2018. Post 5 December 2018, transfer of physical shares will not be permitted, with the exception of the share certificates held under a legal will.

Step-by-step procedure to convert physical shares to Demat:

Holders of share certificates in the physical form can quickly get their shares converted into dematerialised form by following some simple steps as given below:
