Sentences and convictions for conspiring to commit mail and wire fraud in the sale of coins, 18 U.S.C. section 1349, and money laundering, section 1956(a)(1)(A)(i) and 1956(h), are: 1) remanded with respect to restitution and forefeiture where the government concedes on these issues; but 2) affirmed in other respects over clams that the court erred in admitting expert testimony as to the grading and valuation of coins and that the sentences are unreasonable.
