This photo provided by Jim Gross of Marion, Iowa, shows a peeled a potato with a cross design inside that he and his wife Connie discovered on December 31, 2009.
Online bidders may now buy two potatoes containing likenesses of crosses in their centres. One was found by an Iowa family and the other by a police detective in Ohio.
Jim Gross of Marion, Iowa, says his wife was peeling their potato on New Year's Eve when she found the cross shape. The spud is on sale on eBay, with bids starting at $US2. ($NZ2.84.) Dennis Bort of Brunswick, Ohio, says he found the cross shape in his potato on Christmas Day.
Bort listed his spud for $US1,000. He hasn't found any bidders yet.
In the past, collectors have paid big bucks for items deemed to have been blessed by the appearance of a religious symbol, including $US28,000 for a partially eaten grilled cheese sandwich with the likeness of the Virgin Mary.
