The site contains a collection of burial mounds, of which much the most significant is the undisturbed ship burial in Mound 1 containing very rich grave goods including the purse-lid. The person buried in Mound 1 is usually thought to have been Raedwald, King of East Anglia, who died around 624. The purse-lid is considered to be "one of the most remarkable creations of the early medieval period." About seven and a half inches long, it is decorated with beautiful ornament in gold and garnet cloisonné enamel, and was undoubtedly a symbol of great wealth and status. In 2017 the purse-lid was on display at the British Museum.

The purse-lid was the top of a leather pouch for coins. The leather has decayed but forty Frankish coins and two small ingots were found with the lid. Each coin was from a different mint, indicating a deliberately selected collection. The purse hung from the waist belt by the three hinges seen on top of it. The parts of the lid in other non-jewellery materials had decayed, but it probably had a plate behind the metalwork made of valuable whalebone "ivory"; the lid is now displayed with a plain replacement plate, although the original may well have had decorative carving.

The lid formed part of an ensemble of richly decorated fittings to the clothing and weapon worn by the body that were probably made as a set. These consist of a gold belt buckle, and gold and garnet shoulder-clasps, sword harness and scabbard mounts. In particular the purse used a combination of small and large pieces of garnet in a way comparable to the shoulder-clasps. The burial "can be seen as a dramatic expression of the aspirations of East Anglian royalty", within which the ensemble of regalia "is a careful construct; it situates the owner in a dual inheritance of coin-distributing, sceptre-wielding late Roman consuls, and Germanic warrior culture, with its rich iconography of powerful animals, gods and victors."

The lid consists of a kidney-shaped cellwork frame enclosing a sheet of horn, on which were mounted pairs of exquisite garnet cellwork plaques depicting birds, wolves devouring men, geometric motifs and a double panel showing animals with interlaced extremities. The maker derived these images from the ornament of the Swedish-style helmets and shield-mounts also in the burial. In his work they are transferred into the cellwork medium with dazzling technical and artistic virtuosity.

On the outside of the lid there are symmetrical images of a man surrounded by two wolves, a version of the ancient Master of Animals motif. In between these images are two more symmetrical figures, this time depicting an eagle swooping down upon its prey. To the ancient Anglo-Saxons, these images probably held great significance, but to modern historians it is difficult to be sure of the symbolism in these figures. It is possible that the heraldic composition of the men and the wolves alludes to the family name of the Sutton Hoo ship burial – the Wuffingas, or Wolf's People. They could also, along with the eagle, exhibit power, heroism, and courage. Above the animal and human figures the artists inlaid abstract designs.
