They both look good(real) to me. I would say since the serial numbers are almost 200,000 apart from each other the dies might have been touched up a bit during the striking/pressing. Both these bars are from the newer A and B series JM bars that were contract minted by the Sunshine Mint. If you had the older vintage JM bars I would be able to help you a little more with information. However I know for sure most fake and/or silver plated Johnson Matthey bars that are floating around do not have a serial number.
