On the rare 1920 Aachen 75 pfennigs Tombac pattern

I managed to obtain one of these some time ago and discovered this was a rare pattern of 25 minted according to N#317619.

Just curious if there have been past sales of this pattern or how many are in survival mode as of today? Now my specimen has the same diagnostic die crack from the E of Alfred into the field along with light clashing to the left of Rethel.

Topic bump.

Congratulations on this wonderful coin! I hope another one will be auctioned someday, and then I'll have the chance to get it too.
