I wouldn't put a premium on Gilles' note. It's not that close to the range boundary.
I had $5 AOV 5399979, twenty notes removed from the end of the range, and I got about $10 for it in EF condition. That's a good price for an EF, methinks.
I currently have $10 BFF 3639985, fourteen notes from the end of the range. It never occurred to me to ask for a premium.
