The easy answer would be that as Factory 30 was coming to a close they had 350/460 series cards and some newly printed 460 only series cards that were sent to Factory 42 and received the OP. Then Factory 42 continued on with a new run of 460 series cards without the OP.
If I'm understanding you, you think the OP's from the 350/460 series were done at a different time than the 460 Only series. Am I correct? If so I would love to hear your theory.
