I recently noticed that the Tiffany-stamped 5167s I see online have their stamp in one of two places:
1. Vertically centered in the second cell above the 6.

2. Top-aligned in the first cell above the 6.
You can see both variations if you Google image search or search tiffanydial on

Has anyone else noticed this? Any more info/insight?
