Höxter, City of • 50 Pfennigs Alternate color

I've got this notegeld but the one I own has a brownish color instead of the grey in the picture. Should I add it as a different note or as a variant in this page?

Interesting.

I would go for adding it as a separate note as the colour is completely different. 

Alright. New banknoted added : N#529082

Thank you.
