However, #880642 and #880608 have been confirmed to be marked "Adjusted" and features a damaskeening pattern consistent with Grade 925. #880133 and #880855 have been verified as Grade 938. Therefore, this run has been split as follows until futher evidence is discovered: 880001-880500 = 938; 880501-880800 = 925; 880801-881000 = 938.
