1kg Pure Copper Square Bar .9999 Fine German Bullion Sealed Schloss Güldengossa

You get a sealed square bar

Cast in pure copper and marked .9999 fine, this 1kg square bar comes sealed from Schloss Güldengossa. The faces are flat, the edges crisp, with that warm red tone copper gets before it softens with handling. A piece you'd pull for a collection, a desk display, or a sound, dense feel in the hand.

Product specifications stay simple

You're looking at a one-kilo format with a square profile, made from German bullion copper. The seal helps keep the surface protected, so the finish arrives clean and easy to inspect. It's the kind of detail that matters when you want the metal itself, not a polished-up version of it.

It fits collectors and stackers

If you like bars that show weight without bulk, this one does that well. The corners stack neatly, and the broad sides give you room to read the stamp and purity mark at a glance. Heavy, plain, exact. That's the appeal.
