Vintage sterling silver signet ring showcases a genuine Mexican 1943 20 Centavos coin set within a striking brutalist-style mounting. The coin face features the iconic eagle and serpent emblem of the Estados Unidos Mexicanos, while the reverse side displaying the "20 Centavos" denomination is visible through the open back of the setting. The band and bezel are crafted with a heavily textured, bark-like finish that adds a rugged, organic aesthetic to this unique piece of numismatic jewelry. Stamped with a .925 hallmark on the inner band, this ring combines historical currency with bold mid-century design.
