A Tiffany lamp or anything else is only worth what someone is willing to pay on any given day, first of al. That said, you need to be sure it is an authentic lamp by Tiffany Studios, which should be stamp signed on the bottom of the bronze base plate, "Tiffany Studios New York" with a number below that, and usually also on the lower inner metal rim edge "Tiffany Studios New York," - sometimes with a number to the right and sometimes not.
If it has those markings and you know for certain it has been in the some collection or family since 1963 or before, the chances of it being a good forgery can be ruled out.
From there it depends on the glass type (s) used, the colors of the glass in the shade, and the condition of the shade, since the shade is *usually* the most valuable part of a Tiffany Studios table lamp. A great looking shade with 4 hairline cracks can sell for twice what the same shade with 20 cracks and an "out of round" shade might sell for, due to the very high cost of professional, quality restoration. If the lamp you mention by design name is really a "Peacock Table Lamp," they can sell for over $400,000; or if the glass and other things on it are not very vibrant, and the condition is not very good on the shade and/or the base, it can be worth much less.
Tiffany Studios lamp values depend on many things - from the type (s) of glass used, glass colors, shade shape, diameter of the shade, condition, rarity - to other things more esoteric. It's like having two 5 bedroom colonial homes built in 1920, with 5000 square feet and identical floor plans. Once inside especially, one home can have details, condition, and added features that make its eye appeal and value worth twice what the other home is worth. There is no set rule for value when you are dealing with antiques, collectibles and especially things as specialized and individual as Tiffany lamps. That is why there are no "price guides" out for them. What is a $30,000 lamp to ten different collectors might be worth $50-75,00 to someone else who liked the lamp much more for various personal or subjective reasons and who had the extra money to spend to buy it.
