I think the OP is talking about PCGS Gold Shield currency grading and not the gold shield service for coins. It is a bit confusing that PCGS uses the same gold shield labels for the two different services.
My understanding is that PCGS started this service after they licensed the PCGS name to PCGS Currency in order to begin grading currency themselves.
