There's no way they are a match. They are both right sides. But they COULD be from the same buck in different years. It depends on where they were found for color etc, I have found several confirmed year or 2 old BT sheds that were in great shape protected from the sun in deep ferns with good drainage. And depending on the bucks age the difference in bases would make sense. These have enough variation I n the tines it's difficult to say for sure. If it we're me I would compare the pedicles, if off the same deer they will be very, very similar in shape and probably size.
