What do you use to look up prices for rarer obsolete bank notes? I just purchased the Green Sheet online for $5 and was disappointed as expected at how little it covers. No different than the Grey sheet. Maybe there just isn't a price guide for everything that's out there?
I use up to date Auction Archives as a pulse on the Market which is somewhat soft at the moment on some Issues...the rarer high grade Issues are remaining strong in price. RickieB
auction listings are the only way to really get 'up-to-date' and accurate pricing. Guides are pretty much just that
