Oopsies, I hit post before I wanted to, lol. I guess I am a fire engine.
there is only ONE known surviving RADAR note from this bank... there are TWO known common run serial numbers.
All three notes are equally rare. Seeing as it's a rare kind of note that hits the market maybe once a decade, the specialist radar collectors don't have that much better a chance at getting this note, and I don't expect any to be bidding higher than many chartered collectors who have a different kind of appreciation for it. It's just too rare for the radar number to matter. Your shinplaster is a common note type and hence the serial number gives it more value than anything else. Ditto for 1935 BoC issues and many "modern" chartered notes. Justeo's note above is borderline; it might get special attention for its number, but the scarcity of the note type plus its obvious nice condition will play a more important role in determining sale price.
Again, I don't see radar collectors venturing far from BoC notes to find material.
And, oh yeah, all 1870 and 1900 shinplasters are radar notes. Think about it
