Va. Code § 1-504
The lesser seal shall be affixed to all grants for lands and writs of election issued by the Governor; to all letters of pardon and reprieve; to all commissions, civil and military, signed by the Governor, and to all other papers, requiring a seal, authorized to be issued by the Governor for the purpose of carrying the laws into effect within the Commonwealth; and also, when deemed necessary by the Secretary of the Commonwealth, may be used by him as an authentication of his official signature. No tax shall be imposed on the use of such lesser seal, except upon commissions appointing notaries, and commissioners in other states for taking acknowledgments, and upon certificates of the Secretary of the Commonwealth, when, at the request of the parties desiring such certificates, the seal is attached. In all such cases the tax shall be the same as upon the great seal, and shall be collected and accounted for in the same manner.
