Pair of Vintage Silver-Tone Peruvian Mayan/Inca Style Keychains

This is a pair of vintage keychains featuring medallions with Pre-Columbian iconography, likely inspired by Peruvian Inca or Mayan heritage. One medallion is octagonal, while the other is circular, both featuring central embossed figures that resemble deity or warrior motifs, surrounded by a border of a Greek key or 'meander' pattern. The items are fashioned from a silver-toned metal, possibly alpaca silver (a nickel-copper-zinc alloy) or a tarnished sterling silver. Each pendant is suspended by a short cable link chain from a traditional horseshoe-style screw-locking key ring. The metal shows a significant aged patina with dark oxidation in the recessed areas, which helps highlight the intricate relief work. Surface wear, including fine micro-scratches and minor pitting, is consistent with regular use. The overall craftsmanship suggests mid-20th-century souvenir or folk art jewelry, common in South American artisan markets. No visible maker’s marks are present on the front, but the heavy construction and distinctive latch mechanisms indicate a durable industrial design from that era.
