A summary of Southern California-related business litigation developments during the past week.

Rare Coin Investments: A class-action suit was filed against Hannes Tulving Rare Coins Investments, one of the nation’s largest coin dealers, accusing it of “making false or misleading representations” about rare coin investments. The federal lawsuit names only one plaintiff, an investor who purchased $5,000 worth of rare coins in December, 1989. The suit asserts that a prospectus and other material put out to clients by Hannes Tulving falsely stated that rare coins were “the perfect investment” and guaranteed them at 100% for the first year of the investment, a promise the plaintiff said was broken during a recent financial crisis at the dealership. In August, the Federal Trade Commission placed the Newport Beach coin dealership in receivership and filed a lawsuit claiming the firm defrauded investors in a number of ways, including overpricing. Hannes Tulving Jr., the company’s owner, also is named as a defendant in the class-action suit. He has denied allegations of wrongdoing. (Case No. 90-798. Filed Nov. 21, 1990).
