Hi this is pretty much all the info i could find about this collection. The Ultimate Marvel Collection for the collector who loves Marvel Comics, Stamps, Silver or all three! On July 26, 2007, the United States Postal Service issued a sheet of 20 postage stamps featuring the greatest Marvel Comics Super Heroes, including Spider-Man, Captain America, Elektra, the Incredible Hulk, and the Fantastic Four. Marvel's Super Heroes have entertained and inspired generations of Americans ... providing an escape from every day life and making the world a safer place.

I have seen some individual ingots selling on ebay for around $65-$95 each but never a collection this large. This collection includes the custom crafted lacquered wood collector's chest State of the Art Craftsmanship Each stamp ingot and medallion in the The Ultimate Marvel Collection is meticulously crafted by the world’s most skilled artists and minters, Hallmark Group possibly.The painstaking process starts with a steel minting die that is the exact size of the original stamp. When the craftsmen are satisfied that the master die is flawless, only then is it placed into a massive proofing press. Polished .999 fine silver blanks are carefully placed by hand into the press, where they are struck one at a time to create proof-like silver ingots. The medallions are struck using the same process, but with .999 fine silver blanks about the size of a classic U.S. Silver Dollar.For the ingots, perforations are precision diamond cut, then the colorized image of the original stamp is meticulously applied. Colorized images are also precision-applied to the medallions. The colorization is the highest quality in the world, and it brilliantly captures every tiny detail of the original designs. The result is a collection of stunning colorized stamp ingots and medallions that exceeds even the highest standards of excellence. A Message from Stan Lee Dear Friend,I never imagined that characters I created such as Spider-Man, the Fantastic Four, and the Hulk would end up on actual U.S. stamps! But now, I see them staring up at me from real stamps … and I’m thrilled to know that fans everywhere can share my passion for these and other Marvel characters. I was even more ecstatic to be involved in a brand new collection that transforms these postage stamps into limited-edition silver stamp ingots, along with other Marvel Comics characters on matching silver medallions.
