There was some discussion about manually tracking who has a certain serial on some of the less common X-Metals, so that got me thinking. We have almost a decade of collection data to turn to, so I quickly programmed a page that will collate most of that. The top five are listed off the bat, but the full list can be brought up.
Additions to this list are through the Collection Tracker
, by filling in the Serial field for an X-Metal. Do ensure the proper characters and length is correct to ensure consistency.
