Regarding Originating Work Item *****WF********: *We tried to transfer a certificate for which I was custodial account holder for my son in order to transfer this certificate into his name only. We completed the transfer request form and submitted it. However, the value of the certificate was greater than the $*m medallion signature stamp from our bank. In attempting to resolve this issue, I was instructed to submit multiple transfer requests, each with the $*m medallion stamp, in separate envelopes, in order to reach the $**.*m total value of the certificate, and include a letter of explanation. My specific question is: *Should each of these separate requests, in separate envelopes, be mailed individually and separately, or can they be sealed in separate envelopes and then mailed in a single larger envelope?
