feature a printed "2000" to denote its commemorative status. A total of one million ketchup pins were produced, which is roughly the equivalent of a year's worth of pickle pins. Spinoffs and other items Besides the year 2000 ketchup pin, several similar items to the Heinz pickle pin have appeared over the years. A golden lapel pin in the shape of a pickle is a recent example, and Heinz has also made a pickle whistle, presumably as a fun item for kids too young to wear a pin (similar to the Oscar Mayer hot dog whistles distributed from the Wienermobile). In recent years, the amount of Heinz merchandise available has increased to the point that Heinz began operating its own retail store called the House of Heinz, located in Grove City, Pennsylvania.
