I have all four parts of the Garrett Collection catalogs but they are well-used, and the paper seems rather thin and has not held up well. They are nonetheless indispensable in my line of work ... Best Regards, George
The Numismatic Bibliomania Society is where you will find the buyers and sellers of auction catalogs among all other things bookish. I wrote an article about Proof $20 Gold Coins for the Numismatist and bought a couple of auction catalogs for my research. The Trompeter Collection was all high mint state. He called toned coins "shmutzy" (Yiddish: German=schmutzig: dirty. English ~smutty) and wanted "new" (uncirculated) coins. While Eliasberg had all the varieties, not all of his were "new"; some where even shmutzy. I also have some more-or-less "important" (the common word in auctioneering) sales catalogs in other areas. The catalogs provide information not to be found in a common book.
You get what you pay for. There is no sense in regretting your ignorance in the past. I was alive for the Bugs Bunny Franklin Half and the 1955 Doubled Die Lincoln Cent. If you want the catalogues, they are as affordable as any other numismatic item. Dealers ask and arm and leg for them and pay next to nothing. No surprise there. Just saying, you can buy them like anything else. Find the Numismatic Bibliomania Society. Subscribe to the E-Sylum maillist and meet the dealers and other lovers of books, catalogues, ephemera, and related matters.
