Aztec Calendar 5 oz Pure .999 Fine Copper Round Bullion

Feel the 5 oz weight

Five avoirdupois ounces of pure .999 fine copper give you a round with real hand presence. It's thick, smooth at the edge, and has that solid copper weight you notice the moment you pick it up. If you stack metal for the feel of it, this one lands with a satisfying, steady heft.

See the Aztec Sun Stone

The obverse carries a high-relief replica of the Aztec Sun Stone, found in Mexico City in 1790. Tonatiuh sits at the center, with each ring of the calendar cut in sharp detail around him. You can trace the symbols of the four previous eras and catch new lines in the light, which is part of what makes this Copper Round so easy to keep turning in your hand.

Keep the hallmarks clear

The reverse switches to a frosted finish with Cuauhtémoc struck cleanly on the face, along with the exact weight and purity hallmarks. It's the sort of piece that works well in a capsule, a tray, or beside the rest of your physical metal stack when you want history and copper in one place. The detail's crisp, the surfaces have contrast, and it feels made for people who notice small things.
