Antiqued or Tarnished Metal Mug (Bottom View)

This item is identified as the bottom of a metal mug, heavily tarnished or intentionally antiqued, resting on a polished wooden surface. The circular base of the mug is clearly visible, exhibiting a significant amount of dark grey and greenish-brown discoloration, indicative of oxidation and age. The surface texture appears somewhat mottled and uneven, suggesting either a rough casting, significant wear, or a deliberate aged finish. There are no discernible maker's marks, stamps, or signatures visible on the bottom surface due to the heavy patina and the resolution of the image. The material appears to be a base metal, possibly pewter, brass, or copper, given the color of the oxidation, though silver plate cannot be entirely ruled out without further inspection. A small portion of a dark-colored handle is barely visible extending from the side of the mug, suggesting a traditional mug or tankard form. The overall condition suggests a vintage or antique piece that has not been recently polished, or it is designed to mimic such an aesthetic. The craftsmanship cannot be fully assessed from this view alone, but the visible wear and aging contribute to its character. The estimated age is difficult to pinpoint without more visual information, but the tarnish could signify an object from the early to mid-20th century or older if it's a true antique.
