肯尼迪半美元
In March 1970, the two houses reached a compromise whereby 150 million dollars would be struck in the 40% silver alloy for collectors and others. The circulating dollar, though, would have no silver and would be struck in larger quantities. The 47.4 million troy ounces of silver needed to strike the collectors' pieces would come from bullion already held by the government. The compromise was worked out by McClure and other congressional Republicans, with the aid of Brooks, an Idahoan. McClure described the deal as "a lot less than the country deserves, but a lot more than it appeared we would get." The reason for having a collector's edition with silver was to avoid the hoarding which had driven the Kennedy half dollar from circulation.
