Indeed, in 1980, Glenn Seaborg transmuted lead into gold, though the amount of energy used and the microscopic quantities created negated any possible financial benefit.

I think the CRC Handbook says $2,000,000/troy oz. but I don't have a copy with me.
Wikipedia says that a 6.8 MeV gamma ray hitting the stable but rare isotope Hg-198 will result eventually in non-radioactive gold, but I'm having problems confirming that or pricing it. The reverse, sending a neutron into gold to make pure Hg-198 is better known, and verifiable.
