In June 2016 we reported on the 1864 Catalogue of Coins of Mrs. Marshall from the Dave Hirt library. The function of the document wasn't entirely clear - did it represent an actual auction,an exhibit catalog, or a fixed price list? A recent discovery at the ANS answers the question. The back cover of this copy has a penciled inscription:

From this it is clear the document was an exhibit catalog, and one could make a case to classify it as a fixed price list as well. Thanks to Lara Jacobs of Internet Archive, who scans ANS librarymaterials under Newman Portal sponsorship, for bringing this copy to our attention.
