Collectibility
Rimfire ammunition is popular with ammunition cartridge collectors, who base much of the collectibility value of rimfire cartridges on the rarity of the stamped mark on the head of the cartridge (the headstamp). There is a subcategory of collectible rimfire ammunition with headstamps commemorating certain persons who have worked in the industry, often issued in extremely small quantities on the occasion of that person's retirement. Often the majority of these cartridges are given to the retiring individual, leaving him or her to decide to whom they are traded or distributed. This increases their perceived value as collectibles.
