1972-S Eisenhower Dollar encased in a Bezel

This item is a 1972-dated Eisenhower Dollar, prominently featuring the profile of President Dwight D. Eisenhower on the obverse. The coin appears to be an 'S' mint mark (San Francisco) proof or uncirculated strike, though the lighting suggests it may be the 40% silver variety frequently issued in collector sets during that era. The coin is currently housed within a plain, polished silver-tone metal bezel, possibly a coin pendant mount, which encircles the rim. Physical characteristics include the standard 38.1mm diameter of the host coin, though slightly larger with the mounting. The obverse displays the legend 'LIBERTY' across the top and 'IN GOD WE TRUST' to the left of the bust. The condition of the coin shows visible circulation wear or improper storage, with noticeable smudging and perhaps light surface verdigris or environmental toning near the bottom rim around the date. There is a visible gap or irregularity in the bezel at the 9 o'clock position, suggesting it is a tension-fit hobbyist mount rather than a professional jewelry setting. The background includes a scattered assortment of other low-denomination United States and/or international coinage, including fragments of Lincoln cents and potentially Roosevelt dimes, all showing heavy oxidation and circulated patina.
