Although the Mint rarely received deposits of silver for striking into coins after 1853, it purchased silver bullion using the new lightweight silver coins at above-market prices. This was illegal, as Congress had ordered that the new lightweight coins only be purchasable using gold, a provision intended to limit quantities sold to actual demand. As the silver pieces had a legal tender limit of $5, if excessive numbers were circulated, they might choke commerce. This in fact occurred, and merchants and bankers complained that the legal tender limit was causing them to have to sell accumulations at a discount to brokers.
