Where is the W Coin minted?

Could you please clarify for me where exactly the W Coin is minted? I'm curious to know if it's produced in a specific country or region, or if it's a decentralized cryptocurrency that doesn't have a physical location for minting. Additionally, if it's a physical coin, I'd like to know if there are any special processes or materials used in its production. Thank you for your time and assistance in answering this question.
