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.

One of the first Gold Rush-era coins minted in San Francisco, a unique pioneer gold $20 piece minted by John G. Kellogg, will return to the Bay area for just the second time since it was made in 1854.

A unique 1854 Kellogg and Co. $20 pioneer gold piece goes on display again in California, during the first three days of the Long Beach Coin, Stamp, and Collectibles Expo, Jan. 29 to Feb. 1, in the Long Beach Convention Center.
