Hello KelownaGuy,
I think the Devil replacement images suggest a slightly higher grade of AU 55 (AU 50-58). This replacement note is Charlton catalogue BC-29aA and is currently valued around $3,000 in AU grade. Your note is listed in the CPMS registry and is one of 73 currently recorded. It is not scarce, but is a very nice and desirable note!
As mentioned in a previous post, auctions cut into the $$$ you receive in exchange for offering it to more potential bidders. If you search this on iCollector for example, you can see prices of similar notes realized in recent auctions.
Private sales may be better; usually at a slight discount to catalogue. This is great if you can find someone who wants the note. Perhaps someone on this site will be interested.
Cheers,
JBN
