If you are trying to collect a complete set of pins, it is important to find out how many pins there are in the set you are interested in. Sets may range in size from two pins to ten or more pins. In some sets, the pins are all alike except that they come in a number of different colors, and sometimes there may be one special pin that contains all the colors. In other sets, each pin in the set is different. In some sets, each pin can stand alone, and in other sets, you need the whole set in order to have a complete picture, because the pieces fit together like a puzzle. Sometimes one pin in the set will have a higher value than the other pins in the set because there were fewer made, and so it is harder to find. You may have to trade extra pins to get that one more valuable pin in order to complete the set.
