Here's an 1837 Illustrious Predecessor I recently purchased. It's an HT-33, Low-19. It has full cartwheel luster (it's really difficult to take pics of it to show the luster). Carbon spots are detracting from its appeal. It's toned darker with more blues than shown. Reverse is 5% off-center. I'd say this grade: Spoiler: Click for iPen's Grade AU-58 BN Do you agree? Here's a graded version for reference.
