These two coin inlays ARE listed in Archie's book, Sheldon: DBE-1aa and DBE-1bb. Relatively common chips seen at most shows and I'm sure that Albert does have them in his collection.

As you know, the book that illustrates his collection is full of errors so I'm not surprised to see a couple of omissions. I know I frequently confuse the yellow chip with red edge marks with the Dupont Plaza dollar that has identical colors and mold.
