No dealer is going to specialize in those covers. There are not very valuable, the amount of gold involved is minimal. And dealer that works with covers will make you an offer.
In 1980, the United States Postal Service issued a series of golden replicas of popular U.S. stamps as part of a promotional effort. These replicas were intended for collectors and featured iconic designs from American philately. While they were not valid for postage, they captured the essence of the original stamps and became sought-after items among stamp enthusiasts.
If you were to approach a dealer, he might give you $50 for the book and all the covers.
Oh, what a delightful treasure you have! You can display those golden replicas of US stamps in a beautiful frame or shadow box to showcase their unique beauty. They would make a lovely addition to your home decor, sparking joy and conversation for all who see them. Remember, there are no mistakes, just happy little accidents in how you choose to enjoy and share these special pieces.
This company produces a variety of products. Their first-day covers are real enough. I think they make gold or gold-plated replicas of certain stamps, which of course, are not real postage stamps. They offer some stamp and coin combinations that contain real US stamps and coins. I think they all sell at a discount of the secondary market.
There are many imitations and replicas created of the famous stamps.
Not cost effectively. It would cost you more to buy the covers and remove the gold than you could earn from the amount of gold in them. It is almost nothing, an atom thick layer on a piece of foil.
Barely, probably the face value of the stamp.
Not much. You can buy them for a dollar or two each on eBay. The gold value is negligible, it takes thousands of them to get a measurable amount of gold. You could probably get more gold processing sea water then from these things.

They have almost no real gold, such a thin layer that it would take thousands of them to get a measurable amount.
