Medallion signature guarantee program

Get the guaranteed signature you need to sell, redeem or transfer ownership of securities

Whether you are selling, redeeming, or transferring securities such as stocks or mutual funds, the transfer agent will most likely require the signature of the owner(s) to be "guaranteed" by a financial institution before the transaction can be completed. Main Street Bank provides the Medallion Signature Guarantee Service exclusively for shareholders of Main Street Financial Services Corp. (for Main Street Financial Services Corp. stock only) or customers of Main Street Bank. There is a $5.00 fee for this service. 

When a Medallion Stamp is placed on a document, it guarantees the following:

  • A signature is genuine;
  • The signer had legal capacity to sign; and
  • The signer was an appropriate person to endorse the security.

The Medallion Stamp is different than a Notary Stamp/Seal. A Notary Seal is placed on a document, of any kind, and guarantees the signature only. The Medallion guarantees the signature as well as the above-listed items. Also, the Medallion Stamp is only used on securities. A security is an investment instrument such as a stock certificate or a bond.

In order to expedite the Medallion Signature Guarantee process, please bring the following with you to your nearest branch:
