Prices are a guide, not a guarantee

All prices in the book and on this site come from real sales at auctions and on marketplaces, with the place and year of the sale. Prices on the collectibles market change every year. Record prices describe exceptional pieces in exceptional condition; an ordinary example of the same item is usually worth far less. Always check recent completed sales of items in the same variant and condition before you sell.

Not an appraisal

Nothing in the book or on this site is a professional appraisal, authentication, or financial or investment advice. For items that could be valuable, get a certification or an appraisal from a qualified specialist or auction house first.

Safety

Some old items, such as uranium glass, early glazes, old paints and old mechanisms, require care. Follow the handling advice of a specialist and never light candles in old lanterns or run old mechanisms before an inspection.

No affiliation

We are not affiliated with any brand, manufacturer, auction house, grading company or marketplace mentioned. Names are used only to identify items and sources.

AI-created host and images

Richard Hayes, the host of our YouTube channel and the face of this book, is an AI-created character, not a real person. All photographs on this site, including his, are AI-generated illustrations and do not show the specific items whose prices are quoted.
