I have a marble Tiffany Mantle clock – pictures attached. This is an antique – about 1920 and is personally signed by Louis Tiffany inside the clock. it’s about 18 inches long and about 9-10 inches high.

Please advise and I thank you.

What a wonderful clock. First off, I have to disagree somewhat on the age, I believe your clock is a bit earlier than that, this seems to be more in the Victorian Transitional Style rather than a pure Art Deco Period Clock. Therefore I believe it’s circa 1898-1905.

Date Range Made: 1898-1905

Retail Value: $14,500 (Almost anything by Louis Comfort Tiffany should be able to sell easily in the retail range.)

While I’m confident in my knowledge and research on this item, to some degree, what you have is a ‘Wild Card’. By that I mean, that when you have something in a very high value range such as an LCT item or a high end work of art, it could be consigned to auction and shock the audience with outrageous price. There always seems to heated competition for high quality.

Wholesale Value: $10,000 to $12,000
(The midrange price you could expect to achieve at a well advertised live auction. The price that is most often realized for the majority of antiques.)


Quicksale Value: $5,000 to $7000
The price your likely to get if you have to sell your item immediately and your prospective customer is aware of this.

Common Trade Terminology: Tiffany Mantle Clock

Selling Tips: The best venues for selling this are either to a private collector, or consigning to a Major Auction House. It would be possible to sell it online, but not advisable.

Care and Storage Tips: Whenever lifting or moving place the clock gently on a padded surface, antique Marble and Slate can crack with a sudden jolt.
Also, be sure to open the door in the back and remove the pendulum. If shipping, carefully pad and brace the inner works, and of course, double box and pad both the clock and the first box. Run a strip of masking tape along the glass crystal to keep that from breaking as well.

Thanks for your question,
