This is a vintage silver-tone metal stick pin featuring a polished heart-shaped motif on one end and a ribbed decorative cap.

The value of a vintage heart stick pin like this generally ranges between $7 and $25, depending on its brand and exact materials. 

If it is an unbranded, base-metal costume jewelry piece, it typically sells on the lower end around $7 to $12. However, if it is made of solid sterling silver or crafted by a collectible vintage brand (such as Trifari or Anson), its value can rise closer to $20 to $35. Look closely along the needle shaft or behind the heart motif for any small stamps (like "925", "Sterling", or a maker's mark).
