Valuation Breakdown
Current Market Benchmark: An identical "V.O. Sterling" figural bull stick pin in excellent vintage condition recently listed on eBay for $65.00.
General Category Value: Similar mid-century sterling silver animal brooches and corporate/financial theme stick pins generally command between $25 and $75 depending on their condition, patina, and the specific buyer interest in Wall Street or Merrill Lynch collectibles.
Original End Cap: The presence of the matching, ribbed clutch/protector cap is a significant plus for collectors. On the vintage market, missing end caps are the most common flaw for stick pins. Having the original component keeps the piece completely intact and pushes it straight to the top end of the $60 to $65 range.
2.75-Inch Size: The standard length confirms that the long needle shaft is full-sized and has not been historically trimmed, cut down, or shortened to be worn as a standard lapel stud.
Final Market Value Estimate
Because it is fully complete and unaltered, you can confidently value this specific piece at $60.00 – $65.00 based on the current benchmark for this exact hallmark combination
