'Miraculous' cache of 7 century-old baseball cards found

LOS ANGELES — From a crumpled paper bag in a dilapidated house came a baseball-card find of a lifetime. Seven of them actually.

Card experts in Southern California say they have verified the legitimacy — and seven-figure total value — of seven identical Ty Cobb cards from the printing period of 1909 to 1911. Before the recent find, there were only about 15 known to still exist.

Joe Orlando, the president of Professional Sports Authenticator in Newport Beach, California, who verified the find, said in a statement Wednesday that it is "spectacular" and "miraculous" to have come across such a cache.

The family who discovered the cards in a neglected paper bag at the run-down house of a deceased great-grandfather has asked to remain anonymous.
