The contingent buckle for the 21st World Scout Jamboree was made of polished naval brass with a royal blue lacquer.

There are also several collectors buckles made to commemorate specific milestones such as Silver Beaver, Eagle Scout, Wood Badge and Order of the Arrow Vigil Honor, or programs such as the Exploring Division, Region One, Northeast Region, and two Camp Carpenter buckles amongst others.

Some of these buckles were released in unlimited editions to act as a constant fundraiser to sustain the Lawrence L. Lee Scout Museum where they are exclusively available.
