In Iceland they used overstamp/backprint Danish Rigsdaler notes.
So could Rigsdaler Courant be added to the Iceland catalog?
Rigsdaler Courant (1777-1873)
Starting date based on the first notes in the Siegs catalog I sit with, even though, these dates are from the Danish issue of the notes, not the Icelandic overprint.
I'll also ask for the Rigsdaler Rigsmønt (1854-1873) and Krone (1874-1918) to be removed from the catalog. Maybe I missed something, but I can't see any notes nor coins which fit those two currencies when looking thruge books? No coins or notes added to any of these?
Of course feel free to disagree with me :)
