I'm very excited about purchasing a First Edition Whitman blue folder that was one of only two titles not yet confirmed to exist when my book was published last year. This is Whitman's folder 9005 for half dimes 1794-1873, Lange Number W5¢A1.

Before my book revealed how rare this folder is I would have been able to pick it off on eBay for no more than $20-25. By putting my cards on the table, however, it ended up costing me more than $200 to secure this from someone who knew of its rarity from my article in the December, 2020 issue of The Numismatist. I suppose that was inevitable, but I may yet be able to cherrypick another example down the road. I've found that the best way to smoke out rare items is to publish a book on the subject, and that's why I have to issue annual updates to all of my titles.
