Your stamp is AWESOME!
See scan below, may or may not help...
left stamp is 523, two right stamps 547.. difficult to get color right on scanner.
hope this helps but I'm afraid this is exercise in futility (at least for me) without seeing stamps in person--
in grouping below, it is obvious if you saw these stamps together that the one on left is orange red. But on scanner it is hard!
Regardless, centering on your stamp looks like a 95+ grade to me. Good luck
