All 501st patches are considered extremely hard to obtain if not a member. Most patches from the 501st Legion have extremely low production run numbers. For example; 25-50 patches created specifically for a charity, race or benefit. This makes tracking down that particular patch extremely difficult. Note: The 501st organization expressly forbids selling or trading patches outside of the group and violations could result in expulsion from the organization. Online auctions are monitored and in the past have been removed at the 501st Legion’s request. Good luck in your search for any of these patches, for on the secondary market they are very scarce and impossible to acquire.
