VarietyPlus service is also available for coins already encapsulated by NGC.
For coins where the fee column is blank, no VarietyPlus charge is required to
have your coin designated during grading. For coins marked $15, a $15 surcharge
applies to the tier fee during grading, or a $15 fee applies to have the VarietyPlus
designation added to any coin already graded and encapsulated by NGC.
