--Fun Kitchen Collectibles by Jan Lindenberger, 1996 edit., very good book, but prices are very outdated.
--The Complete Book of Kitchen Collecting by Barbara Mauzy; and

Most of the items I sell are listed in the books, however, the book prices on them are very outdated.
Please do not ask me what your items are worth; I am a re-seller, not an appraiser. I value my items based on a cross between book value & market value, and other factors like how long it took me to find the item; the condition of the item; my overhead expenses like rent, commission, gas, mileage, office supplies, wear & tear on my vehicle, time spent looking, etc.
