A 154-year-old $20 gold piece known as the Kellogg Twenty will return to Baltimore next month for the first time in nearly 30 years.

A one-of-a-kind California Gold Rush coin will return to Baltimore for the first time since it was sold by The John Hopkins University more than a quarter century ago.

The unique, first gold coin made for the United States over 200 years ago, the legendary multi-million dollar Brasher Doubloon, will be publicly exhibited in Baltimore for the first time since Johns Hopkins University sold it a quarter-century ago.
