RoundUps are 99.9% pure copper. They are backed with, and simultaneously back, US currency. Each roundUp is issued with a unique identified encryptor (which serves as a "voting key").
NOTE: Due to the recent high volume of business (our retail stores had virtually more business on July 7, 2017, than our ten previous years combined!), roundUps are on back-order. ALL Orders are now being fulfilled with "digital roundUps," which include a unique identifier (a "voting key") enabling the purchaser to vote securely, electronically, and instantaneously, whenever elections are held.
