These are orders for groups of people. This just makes the whole process easier than a bunch of people placing individual orders.
My order of 60 coins is for a group of 20 avid coin collecting geocachers in the SF Bay Area(theGBA.net), as is done in Nurse Dave's group(33 members scattered around the world) the members buy 3 coins each but I consolidate the order into one, saves on shipping, saves forum thread space and makes it easier for the vendor in terms of tracking one order versus 20 individuals and the time saved to pack and ship all of those orders. When combined with NDs group it also allows most people doing a coin to be bumped up into lower pricing for higher volume orders.
Most people in the club keep one in their sig/coin collections and then trade with others locally or afar, some even drop them as very cool trade items or FTF prizes.
