Swiss

Thank you

Dear forum, I am new to this forum and pretty new to the field of collectors. Could someone be so kind and give me any idea how much this note would trade for? First edition 1907 SNB 1000 Swiss Francs. The are a maximum of 37 authentic notes which were not returned and may still exist. Was there ever a public reference sale? Thanks in advance Eric Heavencanwait_@hotmail.com
