Duck Tokens
“Owned by Bartimaeus Bartleby, the Solarium's self-titled “most brilliant dropout”, the Dippy Duck is a magical entertainment complex floating on Lake Grandell. It uses unique duck-stamped tokens as currency for games and gambling.
A beloved novelty, duck tokens are made from pressed sawdust bound with glue. An iridescent, flaky mineral is added to the mix to authenticate real coins and prevent fraud.”
