World Kitchen, which owns the Revere Ware brand along with a number of other iconic brands of yesteryear, no longer sells the classic copper bottom cookware. This is probably a good thing, as the quality of the cookware produced in the last decade was even worse than the rest of the post-1968 cheaper Revere Ware. We have oft heard stories of copper bottoms which appeared almost painted on, or simply fell off completely. I suspect they discontinued the copper bottom cookware because, after decades of poor quality, it had finally cheapened the Revere Ware name.
But you can still find new copper bottom cookware for sale. Consider this one on Amazon.com.
I was shocked to see the high price and the 4-star rating on this piece.
Do yourself a favor if you are looking to replace a sauce pan, or any other Revere Ware piece; buy a used one from eBay or your local thrift store. You can get one for less than half the price shipped and the vintage items (with the double circle process patent stamp) are readily available. They will last you another lifetime.
