How can you tell if an egg that opens to a chess board with little chess pieces in a drawer at the bottom is a Faberge Egg

Fabrege sculpted the famous eggs from fine metals and exquisite jewel quality stones. None were ever made in China. The "Fabrege" name has long been attached to creations of this sort as an indicator or description of style, similar to how the name "Tiffany" is used, rather than denoting the true provenance of the creation.

If it came from the Franklin Mint it's NOT a Fabrege egg. It's a creation crafted in the style of those eggs made for the wife of Nicholas, last Tsar of Russia, by artisans of the Franklin Mint or others.

As a general rule of thumb, creations from the various "mints" that deal in collectibles are priced at the top of their value and can usually only be resold for from 1/3 to as much as 3/4 of their original price. Sometimes a very modest profit can be made but seldom.

A true Fabrege Egg would be worth hundreds of thousands of dollars but few exist outside of museum collections. I believe that fewer than 30 were made, each an exquisite work of unique art. They were birthday gifts for the Tsarina.
