Historical Artifacts

Just a community for everyone to share artifacts, reconstructions, or replicas for the historically-inclined to admire!
Generally, an artifact should be 100+ years old, but this is a flexible requirement if you find something rare and suitably linked to an era of history, not a strict rule. Anything over 100 is fair game regardless of rarity.
Generally speaking, ruins should go to !historyruins@lemmy.world
Illustrations of the past should go to !historyillustrations@lemmy.world
Photos of the past should go to !HistoryPorn@lemmy.world

That doesn't change the fact that cavities are where the material flows. On this mold, the cavities are all the places around the coin.
I suspect this side of the mold is flush with the face of the coin and the other side is recessed to the depth of the coin. That would give the depth of the coin for metal to flow and still make this a workable partial mold.
Or you're completely right and this is an unworkable mold.

If the other side is recessed to the thickness of the coin, then you would have a coin with a giant ring of material protruding off of this side.
