John Sutter was a Swiss settler and investor in the late Mexican era of California. I have only seen secondary sources on the matter, but apparently his colony New Helvetia had bespoke coinage:
... to his other activities he had added the coinage of money, even if it was tin money; pieces of that metal stamped with figures denoting its value and which he accepted in trade at his Fort. -- Watson, The Life of Johann August Sutter
A tin disc with a star inscribed on it...was used as a form of exchange. -- Pierson, Roughing it in Gold Country: Tales from the Mother Lode
Sutter paid the Indians with tin cans, stamped with stars to be used at the company store. -- Ironton Tribute
... he minted tin coins with stars stamped into them for payment to the Indians for work performed and the coins could be redeemed later for food or dry goods in Sutter's store. -- Wells, nevadacounty.com
Does any of these tin coins still exist?
