Coins are much easier to smith than rings. Dunno about the cock-top. I’ve never tried to forge a thimble.

While I suppose you could make a mold and smelt the gold, and I know that gold smelts at a low enough temp they probably could have done exactly that, I don’t know enough of the history of ancient smithing to know when we actually started smelt pouring.

Edit: upon closer inspection, I’m fairly certain that copper/bronze spearhead was smithed not poured.
