Beginning in 1982, all ornaments in the Collector’s Series have been stamped with an identifying Christmas Tree symbol with the ornaments edition number printed in the tree to mark its position in the series. New series are started every year and other series may end. Series designs are offered one per year for a minimum of three years.

Easter series ornaments were marked with an Easter egg symbol.

Two series were ended prior to the third edition; Forever Friends in 2005 and African Holiday BARBIE™ in 1998.
