They're already around half-funded with still a month to go in the campaign.
From the campaign:
Epic Coins are real metal fantasy currency designed to be used with tabletop board games, role playing games, larping or as props. The coins have a fantasy themed design but real world detail and heft, so upgrade your cardboard tokens! There are two unique designs available in sets of 60 pieces (10X cresecent and 50X square coins).
