A Medallion Guarantor bears financial liability should the signature prove to be fraudulent. A medallion signature guarantee is a stamp from an eligible guarantor institution that indicates the individual signing a form is legally authorized to.
Medallion Guarantees are used only in situations involving the sale or transfer of securities. The Medallion indicates that the financial institution named has been defined by SEC Rule 17-Ad15 as an eligible Guarantor and has met all STAMP Program qualifications, including submission of a STAMP Surety Bond.
