This thread (topic 257151) referenced incredible prices being sought on
ebay for certain serial numbers.
This may be a very broad topic, but how much premium exists for Radar notes, single digit notes, etc.?
Here in Canada radar notes are not as popular as they used to be (or so I was told).
Would anyway actually pay 5, 10, 100, 1000 times face value for such a note? That is, assuming the note type itself is otherwise a fairly common one.
