Wyoming legal tender act amendments.

This bill requires Wyoming's state treasurer to accept gold or silver coins (called "specie") as legal payment for state and local taxes, subject to authentication. It mandates the treasurer to set and publish real-time exchange rates between precious metal coins and regular currency, and to exchange these coins for other legal tender. The treasurer must also hold and potentially invest in precious metals, with rulemaking authority to implement these changes. This directly affects taxpayers who pay with coins and the treasurer's office, which gains new duties under the Wyoming Legal Tender Act.
