1 oz Silver Antiqued Legalized DISTRICT OF COLUMBIA. 999 Fine Precious Metal Bullion + COA. Only 500 Antiqued Rounds Produced and Only 12 Rounds in the Complete Set as of Todays Date. As the movement to legalize recreational cannabis across the United States and around the world gained steam, the popularity of the movement has resulted in custom silver round collections celebrating the move toward legalized recreational cannabis. Many of the Legalized Silver Rounds available celebrate each state in the US as it removes the stigma around recreational cannabis use. About the Legalized Collection. The Legalized Collection from Blockchain Mint is designed to represent each individual US state and sovereign nation featured in the series with its own, unique design. In the case of US states or territories, the reverse design field offers a version of the official seal for that jurisdiction. However, each seal has been tweaked to include elements noting the adoption of legal recreational cannabis. In the case of states and territories that use legislation to complete the change, that legislation and the date of its approval are inscribed along with the altered seal. Each of the 1 oz silver rounds in this collection represents a US state or territory that has legalized recreational cannabis, while the 5 oz silver rounds are reserved for sovereign nations that make the move. Both options come with proof and antique versions of each design. The proof rounds have frosted design elements with mirrored background fields, while the antique versions feature a brushed, matte appearance to the visual fields. The Blockchain Mint has limited mintage figures for each design split across the proof and antique versions. All 1 oz state silver rounds have a limited mintage of 500 rounds each for the proof and antique in a given design, totaling 1,000 rounds in all for each state. The nations have a total mintage of 250 rounds per design for a total of 500 for that national design. All individual rounds are housed inside of blister proof cards that include certificate information.
