Hey Bugs mon,
The Special Numbers section of the Charleton appeared on the 3rd edition 1989. It also listed Solids, 2,3,& 4 digit Radars; Ascending, Descending, A/D Ladders, Millions, Low numbered and matching sheet number sets; and a paragraph on Changeover numbered notes. A small section of Paper Money errors is in this edition as well. I recall seeing Millions and radars in shows and collections a few years prior to this publication.
Wow, we won't see these prices anymore. BC-11 1935 $25 Unc for 2,700.
