What is the Value 1941 gold walking liberty half dollar?

It's not gold, it's gold plated. Besides:

> The U.S. never made a gold half dollar. If they had done so it would have been about the diameter of a pencil eraser.

> The U.S. went off the gold standard in 1933 so NO gold coins were made for circulation after that year.

The gold plating would cost more to recover than it's worth. Your coin is considered to be altered or damaged and is only worth its underlying silver metal content, about $6 as of 01/2009
