Well... If you ask me, I'd head to the Bank and have them put in an Order for 30,000 One Dollar Coins... They come in Rolls of 25... But in your case, I imagine the rolls will come in card-board containers... Feel free to read all about my Pocket Change Theory... I have over 300 posts, dealing with the Reset of our U.S. Coinage, with an increased Purchasing Power of 100 Times its current value... I also think that Steemit is so totally Addictive, that it should do a Moon Shot...
