Are there any good price guides out there for Obsolete currency? I collect Iowa Obsoletes and I also like Nebraska Obsoletes. I have the Dean Oaks book on Iowa obsoletes but it does not address any prices. I view auction prices but it seems that rarely are there any Obsolete Iowa currency. I currently receive the following publications: Bank Note Reporter and Coin World.
You might consider looking up Hugh Schull. Deals a lot in stuff like this and heavy on Broken bank notes.
