Vending machine operators have long championed the use of $1 coins because they don't jam the machines, cutting down on repair costs and lost sales. But most people don't seem to like carrying them. In the past five years, the U.S. Mint has produced 2.4 billion Presidential $1 coins. Most are stored by the Federal Reserve, and production was suspended about a year ago.The latest projection from the Government Accountability Office on the potential savings from switching to dollar coins entirely comes as lawmakers begin exploring new ways for the government to save money by changing the money itself. ___ VeriSign wins .com renewal, but can't hike prices NEW YORK (AP) â¿¿ The federal government has cleared VeriSign Inc. to manage the databases that house ".com" domain names for another six years, but the company won't be allowed to raise prices without approval. Under the current contract, which expires Friday, VeriSign was guaranteed four price increases of up to 7 percent each on domain name registrations. VeriSign sought a similar guarantee as part of the contract renewal, but the Commerce Department rejected it. The new contract freezes the annual price at the current $7.85 per name, barring special circumstances. Anyone who wants a ".com" name can obtain one from various companies, which pay VeriSign $7.85 of what they collect on each name. The new contract lets VeriSign continue receiving those fees, but won't guarantee more. ___ US to sell wind energy leases off 3 states PROVIDENCE, R.I.
